Abstract: Inclusive photoproduction of D*+- in ep collisions at HERA has been measured with the ZEUS detector for photon-proton centre of mass energies in the range 115 < W < 280 GeV and photon virtuality Q**2 < 4 GeV**2. The cross section sigma(ep --> D*X) integrated over the kinematic region pt(D*) > 3 GeV and -1.5 < eta(D*) < 1.0 is (10.6+-1.7(stat.)+1.6(syst.)-1.3(syst.)) nb. Differential cross sections as functions of pt(D*), eta(D*) and W are given. The data are compared with two next-to-leading order perturbative QCD predictions. For a calculation using a massive charm scheme the predicted cross sections are smaller than the measured ones. A recent calculation using a massless charm scheme is in agreement with the data., 18 pages including 4 figures

Abstract: In the last few years, many reports have confirmed the presence of WU, KI and Merkel cell (MC) polyomaviruses (PyV) in respiratory samples wordwide, but their pathogenic role in patients with underlying conditions such as cystic fibrosis is still debated. To determine the prevalence of MCPyV, WUPyV and KIPyV, we conducted a 1-year-long microbiological testing of respiratory specimens from 93 patients with cystic fibrosis in Brescia, Italy. We detected PyV DNA in 94 out of 337 analysed specimens. KIPyV was the most common virus detected (12.1%), followed by WUPyV (8.9%) and MCPyV (6.8%). We found an intriguing association between the presence of MCPyV and the concurrent isolation of Pseudomonas aeruginosa, as well as with the patient status, classified as chronically colonized with P. aeruginosa. Our study adds perspective on the prevalence and the potential pathogenic role of PyV infections.

Abstract: The Data Acquisition system for the KLOE experiment, presently running at the Laboratori Nazionali di Frascati DAΦNE collider, has been designed to sustain an acquisition throughput of 50 Mbyte / s for an event rate of 10 kHz . Its two major components are the front end data readout, based on custom buses, and a complex network of computers and storage devices hosting a set of distributed processes. The end result is a seamless data transport from the readout system to the storage library, accompanied by concurrent on line calibrations and data quality control.

Abstract: A small electromagnetic sampling calorimeter, installed in the ZEUS experiment in 1995, significantly enhanced the acceptance for very low x and low Q 2 inelastic neutral current scattering, e+p → e+X, at HERA. A measurement of the proton structure function F2 and the total virtual photon-proton ( γ ∗ p ) cross-section is presented for 0.11 ≤ Q 2 ≤ 0.65 GeV2 and 2 × 10−6 ≤ x ≤ 6 × 10−5, corresponding to a range in the γ ∗ p c.m. energy of 100 ≤ W ≤ 230 GeV. Comparisons with various models are also presented.

Abstract: The CPLEAR collaboration has constructed a detector at CERN for an extensive programme of CP-, T- and CPT-symmetry studies using ${\rm K}^0$ and $\bar{\rm K}^0$ produced by the annihilation of $\bar{\rm p}$'s in a hydrogen gas target. The ${\rm K}^0$ and $\bar{\rm K}^0$ are identified by their companion products of the annihilation ${\rm K}^{\pm} \pi^{\mp}$ which are tracked with multiwire proportional chambers, drift chambers and streamer tubes. Particle identification is carried out with a liquid Cherenkov detector for fast separation of pions and kaons and with scintillators which allow the measurement of time of flight and energy loss. Photons are measured with a lead/gas sampling electromagnetic calorimeter. The required antiproton annihilation modes are selected by fast online processors using the tracking chamber and particle identification information. All the detectors are mounted in a 0.44 T uniform field of an axial solenoid of diameter 2 m and length 3.6 m to form a magnetic spectrometer capable of full on-line reconstruction and selection of events. The design, operating parameters and performance of the sub-detectors are described.}

Abstract: The interference between CP-conserving Ks and K L → π + π − π 0 decay amplitudes was observed by studying the decay rate asymmetries between initial K 0 and K 0 separately for the phase space regions E CM ( π + ) > E CM ( π − ) and E CM ( π + ) E CM ( π − ). For the parameter λ we found Re(λ) = 0.036 ± 0.010(stat.) −0.003 +0.002 (syst.) and Im(λ) consistent with zero, leading to a branching ratio B = [4.1 −1.9 +2.5 (stat.) −0.6 +0.5 (syst.)] × 10 −7 for the CP-conserving K S → π + π − π 0 decay.

Abstract: Antiproton annihilation at rest in gaseous hydrogen (16 bar pressure) to the final states ρ(770)X andf2(1270)X, whereX stands for one or more neutral mesons, has been studied at LEAR using the CPLEAR detector. Relative branching ratios are given forX =π0,2π0, 3π0 ω in the ρ case, and forX =π0, η in thef2 case. The annihilation channel$\bar pp \to \rho 3\pi ^0 $ has not been measured before. The fraction of P-wave annihilation is deduced from the ratiof2π0/ρπ0 to be 0.38±0.07, in good agreement with the result previously obtained by CPLEAR from the ratioK+K-/π+π-.

Abstract: Two-charged-pion correlations were studied in$\bar p$p(→2π*2π−nπ0,n≥0) annihilations at rest with the CPLEAR detector at the Low-Energy Antiproton Ring (LEAR). A strong enhancement was found in the production of pairs of like-sign pions with a small value of the relative fourmomentumQ, with respect to pairs of unlike-sign pions. The observed enhancement was interpreted as a consequence of the Bose-Einstein symmetrization of the two-pion wave function. The data are well represented by a correlation function parametrized as a double-Gaussian; an exponential parametrization is also statistically acceptable. The value of the correlation strength is found to be >1. The high-quality large data samples together with the ability for K± identification and final-state separation allowed the study of systematic effects impacting on theQ dependence of the correlation function and on the extracted space parameters of the pion sources.

Abstract: Bose-Einstein (BE) correlations between like-sign charged pions were studied in pp annihilations at rest into four-prong events, using data taken with the CPLEAR detector at LEAR (CERN). A strong enhancement was found in the production of pairs of like-sign pions of similar momenta, with respect to the pairs of unlike-sign pions. The observed BE- enhancement was used to extract the values for the strength λ of the effect and the radius r of the pion emitting source. The extracted value of λ >l is of relevant importance and clearly does not depend on the assumed parametrization of the correlation function. The influence of the normalization and fitting procedure, the detector resolution, the resonances production and decay and the neutral-pion multiplicity cuts, on the size of the pion source and the strength of the effect was investigated.

Abstract: We report the first determination of CP violation parameters from parameter from particle—antiparticle asymmetry in the decay of neutral kaons into two charged pions. Observation of such an asymmetry is direct proof of CP violation. A fit to the asymmetry enabled a determination of the parameter η+− to be made, yielding the result |η+−|=[2.32±0.14 (stat.)±0.03 (syst.)]×10−3 and σ+−=42.3°±4.4° (stat.)±0.4° (syst.), with an additional uncertainty of ±1.0° due to the error on the present published value of Δm, the KL0-KS0 mass difference. The magnitudes of both statistical and systematic errors will be significantly reduced in the future.

Abstract: The CPLEAR experiment will measure CP violation parameters in the neutral kaon system, using a low energy antiproton beam from the Low Energy Antiproton Ring (LEAR) at CERN. One of its subdetectors, the Particle Identification Detector (PID), makes a fast separation of pions and kaons, which is essential for the experiment. This article describes the design of the PID and its performance during beam tests and during initial runs at LEAR. A pion rejection efficiency of 99.7% for the first level trigger (after 60 ns) is found in the relevant momentum region.

Abstract: The ratio of the branching fractions for p p →K+K− and p p →π+π− was determined with the CPLEAR detector, by stopping antiprotons in a gaseous hydrogen target at 15 bar pressure. It was found to be BR(K+K−)/BR(π+π−)=0.205± 0.016. The fraction of P-wave annihilation at rest at this target density was deduced to be (38±9)%.

Abstract: The first measurement of inclusive Ds+- photoproduction at HERA has been performed with the ZEUS detector for photon-proton centre-of-mass energies 130 < W < 280 GeV. The measured cross section for 3 < pt(Ds) < 12 GeV and |eta(Ds)|< 1.5 is sigma(ep -> Ds X) = 3.79 +- 0.59 (stat.) +0.26-0.46 (syst.) +- 0.94 (br.) nb, where the last error arises from the uncertainty in the Ds decay branching ratio. The measurements are compared with inclusive D*+- photoproduction cross sections in the same kinematic region and with QCD calculations. The Ds cross sections lie above a fixed-order next-to-leading order calculation and agree better with a tree-level O(alpha,alpha_s^3) calculation that was tuned to describe the ZEUS D* cross sections. The ratio of Ds+- to D*+- cross sections is 0.41 +- 0.07 (stat.) +0.03-0.05 (syst.) +- 0.10 (br.). From this ratio, the strangeness-suppression factor in charm photoproduction, within the LUND string fragmentation model, has been calculated to be gamma_s = 0.27 +- 0.05 +- 0.07 (br.). The cross-section ratio and gamma_s are in good agreement with those obtained in charm production in e+e- annihilation., 20 pages, 3 figures, submitted to Phys. Lett. B; 1 footnote added

Abstract: Events containing an isolated prompt photon with high transverse energy, together with a balancing jet, have been observed for the first time in photoproduction at HERA.The data were taken with the ZEUS detector, in a $\gamma p$ centre of mass energy range 120--250 GeV. The fraction of the incoming photon energy participating in the production of the prompt photon and the jet, $x_\gamma$, shows a strong peak near unity, consistent with LO QCD Monte Carlo predictions. In the transverse energy and pseudorapidity range $5\le \eTg < 10$ GeV, $-0.7 \le \eta^\gamma < 0.8$, $\eTj\ge 5$ GeV, and $-1.5\le \eta^{jet}\le 1.8$, with $\xgO > 0.8,$ the measured cross section is $15.3 \pm 3.8 \pm 1.8 pb$, in good agreement with a recent NLO calculation., Comment: 22 pages including 8 figures

Abstract: CP violation has been observed as a time-dependent rate asymmetry between the decays ${⩈erline K}^0 ⌝ghtarrow ≪^{0} ≪^{0}$ and K0 → π0π{0}, where the neutral kaons are produced with definite and individually known strangeness in ${⋏r p}p ⌝ghtarrow{⩈erline K}^0 K^+≪^- $ or pp → K0 K− π+. A special technique for the data analysis has been developed. The values obtained for ϕ00 and ¦ η00¦ are in agreement with those of previous measurements of CP violation.

Abstract: The CPLEAR experiment at CERN measures particle‐antiparticle asymmetries of strangeness‐tagged K0, K0 decays to two‐pion, three‐pion, and semileptonic final states. The technique of CPLEAR is an alternative approach to previous CP‐violation studies. It provides complementary information with different systematics and gives access to novel measurements. The precision of the CP‐violation parameters η+− for π+π−, η+−0 for π+π−π0 and of the T‐violation parameter eT for π±e∓ν will be discussed for the data taken between 1990–1992.

Abstract: The CPLEAR experiment is aiming at precise CP violation tests using initially pure K0- and K0BAR beams from the intense source provided by the annihilation of the LEAR pBAR-beam in hydrogen. The strangeness tagging efficiency and the systematic errors have been studied and found to be in agreement with the design specifications. The measurement of the differential time asymmetry of the pi+pi- decays allowed the direct observation of differences in the decay rates of particles and antiparticles.The CP violating parameters were determined as \eta+/-\ = (2.32 +/- 0.14) . 10(-3) and phi+/- = 42.3-degrees +/- 4.4-degrees. First results in the reconstruction and analysis of the neutral kaon decays into two neutral pions and the K(e)3 decay are presented. Nuclear Physics B

Abstract: The aim of the CP LEAR experiment is to study symmetry-violation effects, making use of tagged K0's and K0's. The detector, although missing some electronic components, has been operational for a few weeks at the end of 1989 at the CERN Low-Energy Antiproton Ring (LEAR). At the moment, the analysis of the data is in progress. This paper gives a description of the experimental method and of the detector; the sensitivities of some measurements and some preliminary results are also discussed.

Abstract: The photoproduction reaction γp → μ+ μ-p has been studied in ep interactions using the ZEUS detector at HERA. The data sample corresponds to an integrated luminosity of 43.2pb-1. The Υ meson has been observed in photoproduction for the first time. The sum of the products of the elastic Υ(1S), Υ(2S),Υ(3S) photoproduction cross sections with their respective branching ratios is determined to be 13.3 ± 6.0(stat.)-2.3+2.7(syst.) pb at a mean photon-proton centre of mass energy of 120 GeV. The cross section is above the prediction of a perturbative QCD model. © 1998 Elsevier Science B.V. All rights reserved.

Abstract: Charged particle production has been measured in deep inelastic scattering (DIS) events over a large range of $x$ and $Q^2$ using the ZEUS detector. The evolution of the scaled momentum, $x_p$, with $Q^2,$ in the range 10 to 1280 $GeV^2$, has been investigated in the current fragmentation region of the Breit frame. The results show clear evidence, in a single experiment, for scaling violations in scaled momenta as a function of $Q^2$., Comment: 21 pages including 4 figures, to be published in Physics Letters B.

Abstract: Differential dijet cross sections have been measured with the ZEUS detector for photoproduction events in which the hadronic final state containing the jets is separated with respect to the outgoing proton direction by a large rapidity gap. The cross section has been measured as a function of the fraction of the photon (ϰγOBS) and pomeron (βOBS) momentum participating in the production of the dijet system. The observed ϰγOBS dependence shows evidence for the presence of a resolved- as well as a direct-photon component. The measured cross section da/dβOBS increases as βOBS increases indicating that there is a sizeable contribution to dijet production from those events in which a large fraction of the pomeron momentum participates in the hard scattering. These cross sections and the ZEUS measurements of the diffractive structure function can be described by calculations based on parton densities in the pomeron which evolve according to the QCD evolution equations and include a substantial hard momentum component of gluons in the pomeron.

Abstract: Author(s): Cattalini, M; Meini, A; Monari, P; Gualdi, G; Arisi, M; Pelucchi, F; Bolognini, S; Gattorno, M; Calzavara-Pinton, PG; Plebani, A | Abstract: Background: Tumor Necrosis Factor Receptor Associated Periodic Syndrome (TRAPS) is a hereditary autoinflammatory syndrome characterized by recurrent episodes of fever and localized inflammation. Clinical presentation can be very variable in terms of duration of fever attacks, periodicity, and accompanying manifestations. One of the most characteristic symptoms is the occurrence of migrating skin rash with myalgia that is sustained by monocytic inflammation.Observations: We herein present the case of a family suffering from TRAPS who had been misdiagnosed for a long period of time and whose main symptom was migrating angioedema. Skin biopsy from one of the patients documented a monocytic panniculitis. All the living patients responded dramatically to anakinra treatment.Conclusions: The classic symptom of migratory angioedema with myalgia in TRAPS can be produced by monocytic panniculitis.This manifestation is so characteristic of TRAPS that its occurrence, even in the absence of other manifestations, should prompt genetic analysis. Our patient’s condition responded promptly to anakinra treatment.

Abstract: In the last few years, many reports have confirmed the presence of WU, KI and Merkel cell (MC) polyomaviruses (PyV) in respiratory samples wordwide, but their pathogenic role in patients with underlying conditions such as cystic fibrosis is still debated. To determine the prevalence of MCPyV, WUPyV and KIPyV, we conducted a 1-year-long microbiological testing of respiratory specimens from 93 patients with cystic fibrosis in Brescia, Italy. We detected PyV DNA in 94 out of 337 analysed specimens. KIPyV was the most common virus detected (12.1%), followed by WUPyV (8.9%) and MCPyV (6.8%). We found an intriguing association between the presence of MCPyV and the concurrent isolation of Pseudomonas aeruginosa, as well as with the patient status, classified as chronically colonized with P. aeruginosa. Our study adds perspective on the prevalence and the potential pathogenic role of PyV infections., (Copyright © 2015 European Society of Clinical Microbiology and Infectious Diseases.
