Abstract

Zusammenfassung: Frakturen des proximalen Humerus im Kindesalter können wegen des hohen Spontankorrekturpotenzials für Fehlstellungen in der Nähe der proximalen Humeruswachstumsfuge in der überwiegenden Mehrzahl der Fälle mit sehr gutem funktionellem Ergebnis konservativ behandelt werden. Ziel dieser Übersicht ist es, die Indikationen und Techniken für die operative Behandlung dieser Verletzungen im Wachstumsalter darzustellen. Indikationen zur primären Reposition und ggf. Stabilisation stellen kosmetisch störende Valgusfehlstellungen bei Kindern und dislozierte proximale Epiphysenlösungen und proximale Humerusfrakturen von vor dem Wachstumsabschluss stehenden Jugendlichen dar, da hier das Remodellingpotenzial fehlt. Während die geschlossene Reposition und perkutane Kirschner-Draht-Fixation von dislozierten proximalen Humerusfrakturen und Epiphysenlösungen sich durch die Möglichkeit die Drahtenden über die Hautoberfläche vorstehen zu lassen und dann ambulant zu entfernen, sowie die meist geringere Durchleuchtungszeit auszeichnet, fehlt dieser Methode die Übungsstabilität im Vergleich zur elastisch stabilen intramedullären Schienung ("elastic stable intramedullary nailing", ESIN). Die ESIN zeichnet sich dagegen durch Übungsstabilität aus, jedoch um den Preis eines 2.Eingriffes in Narkose für die Metallentfernung. Die für die ESIN notwendige exakte Vorreposition für die korrekte Einbringung der Markschienen erfordert meist eine längere Durchleuchtungszeit im Vergleich zur Stabilisation mit perkutan eingebrachten Kirschner-Drähten. Die Interposition von Weichteilen wie Periost oder selten der Sehne des langen Bizepskopfs vorne im Frakturspalt bedingt einen erheblichen Anteil offener Repositionen (bis 50%) bei operativer Frakturstabilisation

Abstract

Background and Purpose— Quantitative T2′ imaging presumably detects regional changes in the relation of oxygenated and deoxygenated hemoglobin. Regional differences in hemoglobin oxygenation might reflect areas with increased oxygen extraction for compensation of reduced perfusion pressure. We investigated quantitative T2′ imaging in patients with high-grade stenoses of brain-supplying arteries and hypothesized that T2′ values are lower in perfusion-restricted areas as compared with normally perfused tissue. Methods— Eighteen patients (15 men; mean age±SD, 54±12.8 years) with unilateral symptomatic or asymptomatic high-grade extracranial or intracranial internal carotid artery or proximal middle cerebral artery stenosis/occlusion were included. MR examination included perfusion-weighted imaging and quantitative, motion-corrected mapping of T2′ time. Time-to-peak and mean transit time maps were thresholded for different degrees of perfusion delays (eg, >0 seconds, ≥2 seconds) compared with the contralateral hemisphere. Mean T2′ values in areas of impaired perfusion were compared with T2′ values in corresponding contralateral or ipsilateral, normoperfused areas. Results— Mean size of perfusion-impaired areas in time-to-peak maps (time-to-peak delay >0 seconds) was 10.8 mL (±6.3) and 11.5 mL (±6.4) in mean transit time maps (mean transit time delay >0 seconds). T2′ values were significantly ( P 0 seconds, T2′ values were 115 ms (±9) versus 125 ms (±12). For mean transit time delay >0 seconds, T2′ values were 115 ms (±9) versus 128 ms (±10). Differences in T2′ values increased with the severity of the perfusion delay. Ipsilateral T2′ values outside the perfusion-disturbed areas did not differ from contralateral T2′ values. Conclusions— Motion-corrected T2′ imaging presumably detects areas with increased oxygen extraction within perfusion-restricted tissue in patients with high-grade occlusive vessel disease.

Abstract

BACKGROUND AND PURPOSE: Cerebral perfusion and O(2) metabolism are affected by physiologic age-related changes. High-resolution motion-corrected quantitative T2′-imaging and PASL were used to evaluate differences in deoxygenated hemoglobin and CBF of the gray matter between young and elderly healthy subjects. Further combined T2′-imaging and PASL were investigated breathing room air and 100% O(2) to evaluate age-related changes in cerebral autoregulation. MATERIALS AND METHODS: Twenty-two healthy volunteers 60–88 years of age were studied. Two scans of high-resolution motion-corrected T2′-imaging and PASL-MR imaging were obtained while subjects were either breathing room air or breathing 100% O(2). Manual and automated regions of interest were placed in the cerebral GM to extract values from the corresponding maps. Results were compared with those of a group of young healthy subjects previously scanned with the identical protocol as that used in the present study. RESULTS: There was a significant decrease of cortical CBF (P < .001) and cortical T2′ values (P < .001) between young and elderly healthy subjects. In both groups, T2′ remained unchanged under hyperoxia compared with normoxia. Only in the younger but not in the elderly group could a significant (P = .02) hyperoxic-induced decrease of the CBF be shown. CONCLUSIONS: T2′-mapping and PASL in the cerebral cortex of healthy subjects revealed a significant decrease of deoxygenated hemoglobin and of CBF with age. The constant deoxyHb level breathing 100% O(2) compared with normoxia in young and elderly GM suggests an age-appropriate cerebral autoregulation. At the younger age, hyperoxic-induced CBF decrease may protect the brain from hyperoxemia.

Abstract

Objective: To elucidate possible mechanisms leading to neurodegeneration in patients with glucocerebrosidase ( GBA )–associated Parkinson disease (PD) using combined proton ( 1 H) and phosphorus ( 31 P) magnetic resonance spectroscopic imaging (MRSI) in vivo. Methods: 1 H and 1 H-decoupled 31 P MRSI was performed in 13 patients with PD with heterozygous GBA mutations (GBA-PD) and 19 age- and sex-matched healthy controls to investigate metabolite concentrations in the mesostriatal target regions of PD pathology. NAA as marker of neuronal integrity, choline and ethanolamine containing compounds as markers of membrane phospholipid metabolism, and energy metabolites (notably high-energy phosphates) were quantified. Results: Compared to controls, NAA was significantly reduced in the putamen ( p = 0.012) and in the midbrain of GBA-PD ( p = 0.05). The choline concentration obtained from 1 H MRSI was significantly decreased in the midbrain of GBA-PD ( p = 0.010). The phospholipid degradation product glycerophosphoethalonamine was increased in the putamen of GBA-PD ( p = 0.05). Changes of energy metabolism were not detected in any region of interest. Conclusion: The pattern of neurodegeneration in GBA -associated PD is more pronounced in the putamen than in the midbrain. Our MRSI findings suggest that the neurodegenerative process in GBA-PD is associated with alterations of membrane phospholipid metabolism which might be also involved in abnormal α-synuclein aggregation.

Abstract

Numerous clinical and research applications for quantitative mapping of the effective transverse relaxation time T*2 have been described. Subject motion can severely deteriorate the quality and accuracy of results. A correction method for T*2 maps acquired with multi-slice multiple gradient echo FLASH imaging is presented, based on acquisition repetition with reduced spatial resolution (and consequently reduced acquisition time) and weighted averaging of both data sets, choosing weighting factors individually for each k-space line to reduce the influence of motion. In detail, the procedure is based on the fact that motion artifacts reduce the correlation between acquired and exponentially fitted data. A target data set is constructed in image space, choosing the data yielding best correlation from the two acquired data sets. The k-space representation of the target is subsequently approximated as linear combination of original raw data, yielding the required weighting factors. As this method only requires a single acquisition repetition with reduced spatial resolution, it can be employed on any clinical system offering a suitable sequence with export of modulus and phase images. Experimental results show that the method works well for sparse motion, but fails for strong motion affecting the same k-space lines in both acquisitions.

Abstract

(1)H MRSI has evolved as an important tool to study the onset and progression of brain damage in multiple sclerosis. Abnormal increases in total creatine, total choline and myoinositol have been noted in multiple sclerosis. However, the pathobiochemical mechanisms related to these changes are still largely unclear. The combination of (1)H MRSI and (1)H-decoupled (31)P MRSI can specify to what extent phosphorylated components of total creatine and total choline contribute to this increase. Combined (1)H and (31)P MRSI data were obtained at 3 T in 22 patients with multiple sclerosis and in 23 healthy controls, and aligned with structural MRI to allow for correction for partial volume effects caused by cerebrospinal fluid and lesion load. A significant increase in total creatine was found in multiple sclerosis, and this was attributed to equal changes in the phosphorylated and unphosphorylated components. The concentrations of the putative glial markers total creatine and myoinositol in lesion-free (1)H MRSI voxels correlated with the global lesion load. We conclude that changes in total creatine are not related to altered energy metabolism, but rather indicate gliosis. Together with the increase in myoinositol, total creatine can be considered as a biomarker for disease severity. A significant total choline increase was mainly a result of choline components not visible by (31)P MRS. The origin of this residual choline fraction remains to be investigated.

Abstract

Mitochondrial dysfunction hypothetically contributes to neuronal degeneration in patients with Parkinson's disease. While several in vitro data exist, the measurement of cerebral mitochondrial dysfunction in living patients with Parkinson's disease is challenging. Anatomical magnetic resonance imaging combined with phosphorus and proton magnetic resonance spectroscopic imaging provides information about the functional integrity of mitochondria in specific brain areas. We measured partial volume corrected concentrations of low-energy metabolites and high-energy phosphates with sufficient resolution to focus on pathology related target areas in Parkinson's disease. Combined phosphorus and proton magnetic resonance spectroscopic imaging in the mesostriatal region was performed in 16 early and 13 advanced patients with Parkinson's disease and compared to 19 age-matched controls at 3 Tesla. In the putamen and midbrain of both Parkinson's disease groups, we found a bilateral reduction of high-energy phosphates such as adenosine triphophosphate and phosphocreatine as final acceptors of energy from mitochondrial oxidative phosphorylation. In contrast, low-energy metabolites such as adenosine diphophosphate and inorganic phosphate were within normal ranges. These results provide strong in vivo evidence that mitochondrial dysfunction of mesostriatal neurons is a central and persistent phenomenon in the pathogenesis cascade of Parkinson's disease which occurs early in the course of the disease.

Abstract

A search for pair production of first-generation leptoquarks LQ is performed with data collected by the D0 experiment in p pbar collisions at sqrt(s)=1.96 TeV at the Fermilab Tevatron Collider. In a sample of data corresponding to ~1 fb-1, the search has been performed on the final states with two electrons and two jets or one electron, two jets and missing transverse energy. We find our data consistent with standard model expectations. The results are combined with those found in a previous analysis of events with two jets and missing transverse energy to obtain scalar LQ mass limits. We set 95% C.L. lower limits on a scalar LQ mass of 299 GeV, 284 GeV and 216 GeV for beta=1, beta=0.5 and beta=0.02 respectively, where beta is the LQ branching ratio in the eq channel. This improves the results obtained with a lower luminosity sample from Run II of the Tevatron. Lower limits on vector LQ masses with different couplings from 357 GeV to 464 GeV for beta=0.5 are also set using this analysis.

Abstract

A search for supersymmetric partners of quarks is performed in the topology of multijet events accompanied by at least one tau lepton decaying hadronically and large missing transverse energy. Approximately 1 fb(-1) of p (p) over bar collision data from the Fermilab Tevatron Collider at a center of mass energy of 1.96 TeV recorded by the D detector is analyzed. Results are combined with the previously published DO inclusive search for squarks and gluinos. No evidence of physics beyond the Standard Model is found and lower limits on the squark mass up to 410 GeV are derived in the framework of minimal supergravity with tan beta = 15, A(0) = -2m(0) and mu < 0, in the region where decays to tau leptons dominate. Gaugino masses m(1/2) are excluded up to 172 GeV.

Abstract

We present a measurement of the top quark pair production cross section in p (p) over bar collisions at root s = 1.96 TeV using approximately 1 fb(-1) collected with the DO detector. We consider decay channels containing two high p(T) charged leptons where one lepton is identified as an electron or a muon while the other lepton can be an electron, a muon or a hadronically decaying tau lepton. For a mass of the top quark of 170 GeV, the measured cross section is 7.5(-1.0)(+1.0)(stat)(-0.6)(+0.7)(syst)(-0.5)(+0.6)(lumi) pb. Using l tau events only, we measure: sigma(t (t) over bar) x B(t (t) over bar -> l tau b (b) over bar) = 0.13(-0.08)(+0.09)(stat)(-0.06)(+0.06)(syst)(-0.02)(+0.02)(lumi) pb. Comparing the measured cross section as a function of the mass of the top quark with a partial next-to-next-to leading order Quantum Chroniodynamics theoretical prediction, we extract a mass of the top quark of 171.5(-8.8)(+9-9) GeV, in agreement with direct measurements.

Abstract

We report results of a search for the pair production of the lightest supersymmetric partner of the top quark, t ˜ 1 , using a data set corresponding to an integrated luminosity of 1 fb −1 collected by the DO detector at a p p ¯ center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. Both scalar top quarks are assumed to decay into a b quark, a charged lepton and a scalar neutrino. The search is performed in the electron plus muon and dielectron final states. The signal topology consists of two isolated leptons, missing transverse energy, and jets. We find no evidence for this process and exclude regions of parameter space in the framework of the minimal supersymmetric standard model.

Abstract

A search for pair production of the lightest supersymmetric partner of the top quark is performed in the lepton+jets channel using 0.9 fb-1 of data collected by the D0 experiment. Kinematic differences between scalar top quark pair production and the dominant top quark pair production background are used to separate the two processes. First limits from Run II of the Fermilab Tevatron Collider for the scalar top quark decaying to a chargino and a b quark are obtained for scalar top quark masses of 130-190 GeV and chargino masses of 90-150 GeV.

Abstract

Indirect evidence from laboratory studies suggests that mitochondrial energy metabolism is impaired in progressive supranuclear palsy (PSP), but brain energy metabolism has not yet been studied directly in vivo in a comprehensive manner in patients. We have used combined phosphorus and proton magnetic resonance spectroscopy to measure adenosine-triphosphate (ATP), adenosine-diphosphate (ADP), phosphorylated creatine, unphosphorylated creatine, inorganic phosphate and lactate in the basal ganglia and the frontal and occipital lobes of clinically probable patients ( N= 21; PSP stages II to III) and healthy controls ( N= 9). In the basal ganglia, which are severely affected creatine in PSP patients, the concentrations of high-energy phosphates (= ATP + phosphorylated creatine) and inorganic phosphate, but not low-energy phosphates (=ADP+ unphosphorylated creatine), were decreased. The decrease probably does not reflect neuronal death, as the neuronal marker N-acetylaspartate was not yet significantly reduced in the early-stage patients examined. The frontal lobe, also prone to neurodegeneration in PSP, showed similar alterations, whereas the occipital lobe, typically unaffected, showed less pronounced alterations. The levels of lactate, a product of anaerobic glycolysis, were elevated in 35% of the patients. The observed changes in the levels of cerebral energy metabolites in PSP are consistent with a functionally relevant impairment of oxidative phosphorylation.

Abstract

We present a search for a narrow scalar or vector resonance decaying into Z gamma with a subsequent Z boson decay into a pair of electrons or moons. The data for this search were collected with the D circle divide detecror at the Fermilab Tevatron p (p) over bar collider at a center of mass energy root s = 1.96 TeV. Using 1.1 (1.0) fb(-1) of data, we observe 49 (50) candidate events in the electron (muon) channel, in good agreement with the standard model prediction. From the combination of both channels, we derive 95% C.L. upper limits on the cross section times branching fraction (sigma x B) into Z gamma. These limits range from 0.19 (0.20) pb for a scalar (vector) resonance mass of 600 GeV/c(2) to 2.5 (3.1) pb for a mass of 140 GeV/c(2).

Abstract

We present a measurement of the cross section for Z boson production times the branching fraction to tau lepton pairs sigma(p (p) over bar -> Z + X)Br(Z -> tau(+)tau(-)) in p (p) over bar collisions at root s = 1.96 TeV. The measurement is performed in the channel in which one tau lepton decays into a muon and neutrinos. and the other tau lepton decays hadronically or into an electron and neutrinos. The data sample corresponds to an integrated luminosity of 1.0 fb(-1) collected with the DO detector at the Fermilab Tevatron Collider. The sample contains 1511 candidate events with an estimated 20% background from jets or muons misidentified as tau leptons. We obtain sigma . Br = 240 +/- 8 (star) +/- 12 (sys) +/- 15 (lum) pb, which is consistent with the standard model prediction.

Abstract

We present new measurements of differential cross sections for Z/gamma*(->mumu)+jet+X production in a 1 fb-1 data sample collected with the D0 detector in proton anti-proton collisions at sqrt{s}=1.96 TeV. Results include the first measurements differential in the Z/gamma* transverse momentum and rapidity, as well as new measurements differential in the leading jet transverse momentum and rapidity. Next-to-leading order perturbative QCD predictions are compared to the measurements, and reasonable agreement is observed, except in the region of low Z/gamma* transverse momentum. Predictions from two event generators based on matrix elements and parton showers, and one pure parton shower event generator are also compared to the measurements. These show significant overall normalization differences to the data and have varied success in describing the shape of the distributions.

Abstract

We present a search for a narrow-width heavy resonance decaying into top quark pairs X->ttbar in ppbar collisions at sqrt{s}=1.96TeV using approximately 0.9fb^-1 of data collected with the D0 detector at the Fermilab Tevatron Collider. This analysis considers ttbar candidate events in the lepton plus jets channel with at least one identified b jet and uses the ttbar invariant mass distribution to search for evidence of resonant production. We find no evidence for a narrow resonance X decaying to ttbar. Therefore, we set upper limits on sigma*B(X->ttbar) for different hypothesized resonance masses using a Bayesian approach. For a Topcolor-assisted technicolor model, the existence of a leptophobic Z' boson with mass M_Z'

Abstract

A search for new physics in the acoplanar jet topology has been performed in 2.5 fb(-1) of data from p (p) over bar collisions at root s = 1.96 TeV, recorded by the DO detector at the Fermilab Tevatron Collider. The numbers of events with exactly two acoplanar jets and missing transverse energy are in good agreement with the Standard Model expectations. The result of this search has been used to set a lower mass limit of 205 GeV at the 95% C.L. on the mass of a scalar leptoquark when this particle decays exclusively into a quark and a neutrino. In the framework of the Little Higgs model with T-parity, limits have also been obtained on the T-odd quark mass as a function of the T-odd photon mass.

Abstract

We present a measurement of the fraction of inclusive W +jets events produced with net charm quantum number 11, denoted W + c-jet, in p collisions at root s = 1.96 TeV using approximately 1 fb(-1) of data collected by the DO detector at the Fermilab Tevatron Collider. We identify the W +jets events via the leptonic W boson decays. Candidate W + c-jet events are selected by requiring a jet containing a muon in association with a reconstructed W boson and exploiting the charge correlation between this muon and W boson decay lepton to perform a nearly model-independent background subtraction. We measure the fraction of W + c-jet events in the inclusive W +jets sample for jet PT > 20 GeV and pseudorapidity |eta| < 2.5 to be 0.074 +/- 0.019(stat.) +/-(0.012)(0.014) (syst.), in agreement with theoretical predictions. The probability that background fluctuations could produce the observed fraction of W + c-jet events is estimated to be 2.5 x 10(-4), which corresponds to a 3.5 sigma statistical significance.

Abstract

The osseous ankle configuration (tibiotalar sector, talar radius and height) has been discovered as intrinsic risk factor for chronic ankle instability (CAI). These measurements were done on lateral radiographs only. In this study, the osseous characteristics in the frontal plane and further lateral values were measured.Level III case-control study.Radiological measurement of frontal and lateral radiographs by one independent, blinded radiologist using a digital DICOM/PACS system.A group of 52 patients with CAI was compared with an age- and sex-matched control group of 52 healthy subjects.In the frontal plane, the depth of the talar curvature (frontal curvature (froCu)) and the lateral and medial malleolar lengths were measured. In the lateral plane, the position of the centre of rotation to the tibial axis (talar centre of rotation to the anatomical axis of the tibia (TibCOR)) and the tibial lateral surface angle (TLS) were also measured.The froCu was deeper in patients with CAI (1.8 (0.5) mm) than in healthy subjects (1.0 (0.5) mm, p0.05). The TibCOR was more anterior in patients with CAI (2.5 (1.9) mm) than in healthy subjects (1.6 (2.2) mm, p0.05). The distance from the fibular tip to the centre of rotation was smaller in patients with CAI (3.5 (3.4) mm) than in healthy subjects (6.5 (3.3) mm, p0.05). The TLS and the length of the lateral and medial ankle were not significantly different.This study supports that the osseous joint configuration is an intrinsic risk factor for CAI. It could be shown that CAI is characterised by a deeper frontal curvature of the talus and a more anterior position of the talus to the tibia.

Abstract

Mitochondrial complex I appears to be dysfunctional in progressive supranuclear palsy (PSP). Coenzyme Q(10) (CoQ(10)) is a physiological cofactor of complex I. Therefore, we evaluated the short-term effects of CoQ(10) in PSP. We performed a double-blind, randomized, placebo-controlled, phase II trial, including 21 clinically probable PSP patients (stage < or = III) to receive a liquid nanodispersion of CoQ(10) (5 mg/kg/day) or matching placebo. Over a 6-week period, we determined the change in CoQ(10) serum concentration, cerebral energy metabolites (by (31)P- and (1)H-magnetic resonance spectroscopy), motor and neuropsychological dysfunction (PSP rating scale, UPDRS III, Hoehn and Yahr stage, Frontal Assessment Battery, Mini Mental Status Examination, Montgomery Asberg Depression Scale). CoQ(10) was safe and well tolerated. In patients receiving CoQ(10) compared to placebo, the concentration of low-energy phosphates (adenosine-diphosphate, unphosphorylated creatine) decreased. Consequently, the ratio of high-energy phosphates to low-energy phosphates (adenosine-triphosphate to adenosine-diphosphate, phospho-creatine to unphosphorylated creatine) increased. These changes were significant in the occipital lobe and showed a consistent trend in the basal ganglia. Clinically, the PSP rating scale and the Frontal Assessment Battery improved slightly, but significantly, upon CoQ(10) treatment compared to placebo. Since CoQ(10) appears to improve cerebral energy metabolism in PSP, long-term treatment might have a disease-modifying, neuroprotective effect.

Abstract

We present new results of the search for WH→ℓνbb¯ production in pp¯ collisions at a center-of-mass energy of s=1.96 TeV, based on a dataset with integrated luminosity of 0.44 fb−1. We combine these new results with previously published searches by the D0 collaboration, for WH and ZH production analyzed in the E̸Tbb¯ final state, for ZH (→ℓ+ℓ−bb¯) production, for WH (→WWW) production, and for H (→WW) direct production. No signal-like excess is observed either in the WH analysis or in the combination of all D0 Higgs boson analyses. We set 95% C.L. (expected) upper limits on σ(pp¯→WH)×B(H→bb¯) ranging from 1.6 (2.2) pb to 1.9 (3.3) pb for Higgs boson masses between 105 and 145 GeV, to be compared to the theoretical prediction of 0.13 pb for a Standard Model (SM) Higgs boson with mass mH=115 GeV. After combination with the other D0 Higgs boson searches, we obtain for mH=115 GeV an observed (expected) limit 8.5 (12.1) times higher than the SM predicted Higgs boson production cross section. For mH=160 GeV, the corresponding observed (expected) ratio is 10.2 (9.0).

Abstract

A data sample corresponding to an integrated luminosity of 2.1 fb(-1) collected by the D phi detector at the Fermilab Tevatron Collider was analyzed to search for squarks and gluinos produced in p (p) over bar collisions at a center-of-mass energy of 1.96 TeV. No evidence for the production of such particles was observed in topologies involving jets and missing transverse energy, and 95% C.L. lower limits of 379 GeV and 308 GeV were set on the squark and gluino masses, respectively, within the framework of minimal supergravity with tan beta = 3, A(0) = 0, and mu < 0. The corresponding previous limits are improved by 54 GeV and 67 GeV.

Abstract

We report results of a search for supersymmetry (SUSY) with gauge-mediated symmetry breaking in di-photon events collected by the DO experiment at the Fermilab Tevatron Collider in 2002-2006. In 1.1 fb(-1) of data, we find no significant excess beyond the background expected from the standard model and set the most stringent lower limits to date for a standard benchmark model on the lightest neutralino and chargino masses of 125 GeV and 229 GeV, respectively, at 95% confidence.

Abstract

We present a study of events with Z bosons and jets produced at the Fermilab Tevatron Collider in ppbar collisions at a center of mass energy of 1.96 TeV. The data sample consists of nearly 14,000 Z/G* -> e+e- candidates corresponding to the integrated luminosity of 340 pb-1 collected using the D0 detector. Ratios of the Z/G* + >= n jet cross sections to the total inclusive Z/G* cross section have been measured for n = 1 to 4 jet events. Our measurements are found to be in good agreement with a next-to-leading order QCD calculation and with a tree-level QCD prediction with parton shower simulation and hadronization.

Abstract

We present a study of eey and mu mu gamma events using 1109 (1009) pb-(1) of data in the electron (muon) channel, respectively. These data were collected with the DO detector at the Fermilab Tevatron pp collider at Is = 1.96 TeV. Having observed 453 (515) candidates in the eey (jtAy) final state, we measure the Z gamma production cross section for a photon with transverse energy ET > 7 GeV, separation between the photon and leptons Delta Rey > 0.7, and invariant mass of the di-lepton pair Mee > 30 GeV/(2)(c), to be 4.96 0.30(stat. + syst.) zE 0.30(lumi.) pb, in agreement with the Standard Model prediction of 4.74 0.22 pb. This is the most precise Zy cross section measurement at a hadron collider. We set limits on anomalous trilinear Zyy and ZZy gauge boson couplings of -0.085 < h(30)(y) < 0.084, -0.0053 < h(40)(y) < 0.0054 and -0.083 < h(30)(Z) < 0.082, 30 40 30 -0.0053 < h(40)(Z) < 0.0054 at the 95% C.L. for the form-factor scale A = 1.2 TeV. 40 .

Abstract

We report on a search for second generation leptoquarks LQ_2 which decay into a muon plus quark in p\bar{p} collisions at a center-of-mass energy of sqrt{s} = 1.96 TeV in the D0 detector using an integrated luminosity of about 300 pb-1. No evidence for a leptoquark signal is observed and an upper bound on the product of the cross section for single leptoquark production times branching fraction beta into a quark and a muon was determined for second generation scalar leptoquarks as a function of the leptoquark mass. This result has been combined with a previously published D0 search for leptoquark pair production to obtain leptoquark mass limits as a function of the leptoquark-muon-quark coupling, lambda. Assuming lambda=1, lower limits on the mass of a second generation scalar leptoquark are m{LQ_2}>274 GeV and m{LQ_2}>226 GeV for beta=1 and beta=1/2, respectively.

Abstract

A search for the pair production of scalar top quarks, {bar t}, has been performed in 360 pb{sup -1} of data from p{bar p} collisions at a center-of-mass energy of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron collider. The {bar t} decay mode considered is {bar t} {yields} c{bar {chi}}{sub 1}{sup 0}, where {bar {chi}}{sub 1}{sup 0} is the lightest supersymmetric particle. The topology analyzed therefore consists of a pair of acoplanar heavy-flavor jets with missing transverse energy. The data show good agreement with the standard model expectation, and a 95% C.L. exclusion domain in the (m{sub {tilde t}}, m{sub {tilde {chi}}{sub 1}{sup 0}}) plane has been determined, extending the domain excluded by previous experiments.

Abstract

We describe a search for the Standard Model Higgs boson with a mass of 105 GeV/c(2) to 145 GeV/c(2) in data corresponding to an integrated luminosity of approximately 450 pb(-1) collected with the D phi detector at the Fermilab Tevatron p (p) over bar collider at a center-of-mass energy of 1.96 TeV. The Higgs boson is required to be produced in association with a Z boson, and the Z boson is required to decay to either electrons or muons with the Higgs boson decaying to a b (b) over bar pair. The data are well described by the expected background, leading to 95% confidence level cross section upper limits sigma (p (p) over bar -> ZH) x B(H -> b (b) over bar) in the range of 3.1 pb to 4.4 pb.
