Abstract: An angular analysis of B{sup 0}{yields}J/{psi}K*{sup 0} and B{sup 0}{sub s}{yields}J/{psi}{phi} has been used to determine the decay amplitudes with parity-even longitudinal (A{sub 0}) and transverse (A{sub {parallel}}) polarization and parity-odd transverse (A{sub {perpendicular}}) polarization. The measurements are based on 190 B{sup 0} and 40 B{sup 0}{sub s} candidates obtained from 89 pb{sup -1} of p{ovr p} collisions at the Fermilab Tevatron. The longitudinal decay amplitude dominates with |A{sub 0}|{sup 2} = 0.59{+-}0.06{+-}0.01 for B{sup 0} and |A{sub 0}|{sup 2} = 0.61{+-}0.14{+-}0.02 for B{sup 0}{sub s} decays. The parity-odd amplitude is found to be small with |A{sub {perpendicular}}|{sup 2} = 0.13{sub -0.09}{sup +0.12}{+-}0.06 for B{sup 0} and |A{sub {perpendicular}}|{sup 2} = 0.23{+-}0.19{+-}0.04 for B{sup 0}{sub s} decays.

Abstract: This Letter describes a direct measurement of the W boson total decay width, {Gamma}{sub W}, using the Collider Detector at Fermilab. The measurement uses an integrated luminosity of 90 pb{sup -1}, collected during the 1994-1995 run of the Fermilab Tevatron p{anti p} collider. The width is determined by normalizing predicted signal and background distributions to 49 844 W {yields}e{nu} candidates and 21 806 W{yields}{mu}{nu} candidates in the transverse-mass region M{sub T}

Abstract: We have measured the polarization of J/psi and psi(2S) mesons produced in pp collisions at sqrt[s] = 1.8 TeV, using data collected at the Collider Detector at Fermilab during 1992-1995. The polarization of promptly produced J/psi [psi(2S)] mesons is isolated from those produced in B-hadron decay, and measured over the kinematic range 4 [5.5]

Abstract: We report the results of a search for second and third generation leptoquarks using 88 pb{sup -1} of data recorded by the Collider Detector at Fermilab. Color triplet technipions, which play the role of scalar leptoquarks, are investigated due to their potential production in decays of strongly coupled color octet technirhos. Events with a signature of two heavy flavor jets and missing energy may indicate the decay of a second (third) generation leptoquark to a charm (bottom) quark and a neutrino. As the data are found to be consistent with standard model expectations, mass limits are determined.

Abstract: We use 106 pb{sup -1} of data collected with the Collider Detector at Fermilab to search for narrow-width, vector particles decaying to a top and an antitop quark. Model independent upper limits on the cross section for narrow, vector resonances decaying to t{ovr t} are presented. At the 95% confidence level, we exclude the existence of a leptophobic Z' boson in a model of top-color-assisted technicolor with mass M{sub Z'}

Abstract: Events collected by the Collider Detector at Fermilab (CDF) with an energetic jet plus large missing transverse energy can be used to search for physics beyond the standard model. We see no deviations from the expected backgrounds and set upper limits on the production of new processes. We consider in addition the production of light gravitinos and set a limit at 95% confidence level on the breaking scale root F greater than or equal to 217 GeV, which excludes gravitino masses smaller than 1.1 X 10(-5) eV/c(2).

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We have searched for direct production of scalar top quarks at the Collider Detector at Fermilab in 88 pb{sup -1} of pp collisions at {radical}(s)=1.8 TeV . We assume the scalar top quark decays into either a bottom quark and a chargino or a bottom quark, a lepton, and a scalar neutrino. The event signature for both decay scenarios is a lepton, missing transverse energy, and at least two b -quark jets. For a chargino mass of 90 GeV/c{sup 2} and scalar neutrino masses of at least 40 GeV/c{sup 2} , we find no evidence for scalar top production and present upper limits on the production cross section in both decay scenarios.

Abstract: We have reconstructed the radiative decays chi(b)(1P)-->Upsilon(1S)gamma and chi(b)(2P)-->Upsilon(1S)gamma in pp collisions at sqrt[s] = 1.8 TeV, and measured the fraction of Upsilon(1S) mesons that originate from these decays. For Upsilon(1S) mesons with p(Upsilon)(T)>8.0 GeV/c, the fractions that come from chi(b)(1P) and chi(b)(2P) decays are [27.1+/-6.9(stat)+/-4. 4(syst)]% and [10.5+/-4.4(stat)+/-1.4(syst)]%, respectively. We have derived the fraction of directly produced Upsilon(1S) mesons to be [50.9+/-8.2(stat)+/-9.0(syst)]%.

Abstract: We have studied the production of B hadrons in 1.8-TeV pp(bar sign) collisions. We present measurements of the fragmentation fractions, f{sub u} , f{sub d} , f{sub s} , and f{sub baryon} , of produced b quarks that yield B{sup +} , B{sup 0} , B{sup 0}{sub s} , and {lambda}{sup 0}{sub b} hadrons. Reconstruction of five electron-charm final states yields f{sub s}/( f{sub u}+f{sub d})=0.213{+-}0.068 and f{sub baryon}/( f{sub u}+f{sub d})=0.118{+-}0.042 , assuming f{sub u}=f{sub d} . If all B hadrons produced in pp(bar sign) collisions cascade to one of these four hadrons, we determine f{sub u}=f{sub d}=0.375{+-}0.023 , f{sub s}=0.160{+-}0.044 , and f{sub baryon}=0.090{+-}0.029 . If we do not assume f{sub u}=f{sub d} , we find f{sub d}/f{sub u}=0.84{+-}0.16 . (c) 2000 The American Physical Society.

Abstract: We search for color singlet technirho and technipion production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$ recorded with the Collider Detector at Fermilab. These exotic technimesons are present in a model of walking technicolor. The signatures studied are lepton plus two jets plus ${E}_{T}$ and multijet final states. No excess of events is seen in either final state. We set an upper limit on the technirho production cross section and exclude a region in the technipion mass versus technirho mass plane.

Abstract: We present the results of a search for pair production of a fourth-generation charge -1 / 3 quark (b(')) in sqrt[s] = 1.8 TeV pp collisions using 88 pb(-1) of data obtained with the Collider Detector at Fermilab. We assume that both quarks decay via the flavor-changing neutral current process b(')-->bZ(0) and that the b(') mass is greater than m(Z)+m(b). We studied the decay mode b(')b(');-->Z(0)Z(0)bb where one Z0 decays into e(+)e(-) or m(+)m(-) and the other decays hadronically, giving a signature of two leptons plus jets. An upper limit on the sigma(pp-->b(')b(');)x[B(b(')-->bZ(0))](2) is established as a function of the b(') mass. We exclude at 95% confidence level a b(') quark with mass between 100 and 199 GeV/c(2) for B(b(')-->bZ(0)) = 100%.

Abstract: We report on a search for the flavor-changing neutral current decays B{sup +} {yields} {mu}{sup +}{mu}{sup -}K{sup +} and B{sup 0} {yields} {mu}{sup +}{mu}{sup -}K{sup *0} using 88 pb{sup -1} of data from p{ovr p} collisions at sqrt[s] = 1.8 TeV, collected with the Collider Detector at Fermilab. Finding no evidence for these decays, we set upper limits on the branching fractions B(B{sup +} {yields} {mu}{sup +}{mu}{sup -}K{sup +})

Abstract: We have measured the number of like-sign (LS) and opposite-sign (OS) lepton pairs arising from double semileptonic decays of $b$ and $\bar{b}$-hadrons, pair-produced at the Fermilab Tevatron collider. The data samples were collected with the Collider Detector at Fermilab (CDF) during the 1992-1995 collider run by triggering on the existence of $\mu \mu$ and $e \mu$ candidates in an event. The observed ratio of LS to OS dileptons leads to a measurement of the average time-integrated mixing probability of all produced $b$-flavored hadrons which decay weakly, $\bar{\chi} = 0.152 \pm 0.007$ (stat.) $\pm 0.011$ (syst.), that is significantly larger than the world average $\bar{\chi} = 0.118 \pm 0.005$., Comment: 47 pages, 10 figures, 15 tables Submitted to Phys.

Abstract: We measure the relative rate of production of orbitally excited (L = 1) states of B mesons (B**) by observing their decays into B pi (+/-). We reconstruct B mesons through semileptonic decay channels using data collected in p(p) over bar collisions at roots = 1.8 TeV. The fraction of light B mesons that are produced as L = 1B** states is measured to be 0.28 +/- 0.06(stat) +/- 0.03(syst). We also measure the collective mass of the B** states, and quantify the result by quoting the (model-dependent) mass of the lowest B** state to be m(B-1) = 5.71 +/- 0.02 GeV/c(2).

Abstract: We present a study of events with W bosons and hadronic jets produced in p{anti p} collisions at a center of mass energy of 1.8 TeV. The data consist of 51400 W {yields} e {nu} decay candidates from 108 pb{sup -1} of integrated luminosity collected using the CDF detector at the Fermilab Tevatron collider. Cross sections and jet production properties have been measured for W + {>=} 1 to {>=} 4 jet events. The data compare well to predictions of leading-order QCD matrix element calculations with added gluon radiation and simulated parton fragmentation.

Abstract: We report on the first measurement of the rapidity distribution dsigma/dy over nearly the entire kinematic region of rapidity for e^+e^- pairs in the Z-boson region of 66 116 GeV/c^2. The data sample consists of 108 pb^{-1} of ppbar collisions at \sqrt{s}=1.8 TeV taken by the Collider Detector at Fermilab during 1992--1995. The total cross section in the $Z$-boson region is measured to be 252 +- 11 pb. The measured total cross section and d\sigma/dy are compared with quantum chromodynamics calculations in leading and higher orders.

Abstract: Top quark production offers the unique opportunity to search for a charged Higgs boson (H{sup {+-}}), as the contribution from t{yields}H{sup +}b{yields}{tau}{sup +}{nu}b can be large in extensions of the standard model. We use results from a search for top quark pair production by the Collider Detector at Fermilab (CDF) in the e{tau}+Ee{sub T}+jets and {mu}{tau}+Ee{sub T}+jets signatures to set an upper limit on the branching ratio of B(t{yields}H{sup +}b) in 106 pb{sup -1} of data. The upper limit is in the range 0.5 to 0.6 at 95% C.L. for H{sup +} masses in the range 60 to 160 GeV, assuming the branching ratio for H{sup +}{yields}{tau}{nu} is 100%. The {tau} lepton is detected through its 1-prong and 3-prong hadronic decays. (c) 2000 The American Physical Society.

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We present a measurement of the cross section for production of two or more jets as a function of dijet mass, based on an integrated luminosity of 86 pb{sup -1} collected with the Collider Detector at Fermilab. Our dijet mass spectrum is described within errors by next-to-leading order QCD predictions using CTEQ4HJ parton distributions, and is in good agreement with a similar measurement from the DOe experiment.

Abstract: This paper reports an updated measurement of the standard model CP violation parameter sin 2{beta} using the CDF Detector at Fermilab. The entire run I data sample of 110 pb{sup -1} of proton-antiproton collisions at {radical}(s)=1.8 TeV is used to identify a signal sample of {approx}400 B{yields}J/{psi} K{sub S}{sup 0} events, where J/{psi}{yields}{mu}{sup +}{mu}{sup -} and K{sub S}{sup 0}{yields}{pi}{sup +}{pi}{sup -}. The flavor of the neutral B meson is identified at the time of production by combining information from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to determine sin 2{beta}=0.79{sub -0.44}{sup +0.41}(stat+syst). This value of sin 2{beta} is consistent with the standard model prediction, based upon existing measurements, of a large positive CP-violating asymmetry in this decay mode.

Abstract: The oscillation frequency {delta}m{sub d} of B{sup 0}B(bar sign){sup 0} mixing is measured using the partially reconstructed semileptonic decay B(bar sign){sup 0}{yields}l{sup -}{nu}(bar sign)D{sup *+}X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992-1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb{sup -1} of p(bar sign)p collisions at {radical}(s)=1.8 TeV. We estimate the proper decay time of the B(bar sign){sup 0} meson from the measured decay length and reconstructed momentum of the l{sup -}D{sup *+} system. The charge of the lepton in the final state identifies the flavor of the B(bar sign){sup 0} meson at its decay. The second lepton in the event is used to infer the flavor of the B(bar sign){sup 0} meson at production. We measure the oscillation frequency to be {delta}m{sub d}=0.516{+-}0.099{sub -0.035}{sup +} {sup 0.029} ps{sup -1}, where the first uncertainty is statistical and the second is systematic.

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We have studied the production of B hadrons in 1.8-TeV pp[over ¯] collisions. We present measurements of the fragmentation fractions, f_{u}, f_{d}, f_{s}, and f_{baryon}, of produced b quarks that yield B^{+}, B^{0}, B_{s}^{0}, and Λ[over ¯]_{b}^{0} hadrons. Reconstruction of five electron-charm final states yields f_{s}/( f_{u}+f_{d})=0.213±0.068 and f_{baryon}/( f_{u}+f_{d})=0.118±0.042, assuming f_{u}=f_{d}. If all B hadrons produced in pp[over ¯] collisions cascade to one of these four hadrons, we determine f_{u}=f_{d}=0.375±0.023, f_{s}=0.160±0.044, and f_{baryon}=0.090±0.029. If we do not assume f_{u}=f_{d}, we find f_{d}/f_{u}=0.84±0.16.
