Measurement of correlated μ−overlineb\mu - {overline b} jet cross sections in ppˉp {\bar p} collisions at s=1.8\sqrt{s}=1.8 TeV

We report on measurements of differential $\mu - {\bar b}$ cross sections, where the muon is from a semi-leptonic $b$ decay and the ${\bar b}$ is identified using precision track reconstruction in jets. The semi-differential correlated cross sections, d$\sigma$/d\Et^{{\bar b}}, d$\sigma$/d\pt^{{\bar b}}, and d$\sigma$/d$\delta\phi(\mu - {\bar b})$ for \pt^{\mu}>~9 GeV/c, $|\eta^{\mu}|$~10 GeV, $|\eta^{{\bar b}}|<$~1.5, are presented and compared to next-to-leading order QCD calculations.Comment: Uses Latex, Article 12 point, figures appended as uuencoded file The full PostScript available via WWW at http://www-cdf.fnal.gov/physics/pub95/cdf3164_mu_bbar_prd_final.p

Measurement of the BB Meson Differential Cross Section, dσ/dpTd\sigma/dp_T, in ppˉp\bar{p} Collisions at s=1.8\sqrt{s} = 1.8 TeV

This paper presents the first direct measurement of the $B$ meson differential cross section, $d\sigma/dp_T$, in $p\bar{p}$ collisions at $\sqrt{s}=1.8$ TeV using a sample of $19.3 \pm 0.7$ pb$^{-1}$ accumulated by the Collider Detector at Fermilab (CDF). The cross section is measured in the central rapidity region $|y| 6.0$ GeV/$c$ by fully reconstructing the $B$ meson decays $B^{+}\to J/\psi K^{+}$ and $B^{0}\to J/\psi K^{*0}(892)$, where $J/\psi \to \mu^+\mu^-$ and $K^{*0} \to K^+ \pi^-$. A comparison is made to the theoretical QCD prediction calculated at next-to-leading order.Comment: 14 pages. Submitted to Phys. Rev. Lett.

The Charge Asymmetry in W-Boson Decays Produced in p-pbar Collisions at sqrt(s) = 1.8 TeV

The charge asymmetry has been measured using $19,039~W$ decays recorded by the CDF detector during the 1992-93 run of the Tevatron Collider. The asymmetry is sensitive to the ratio of $d$ and $u$ quark distributions to $x<0.01$ at $Q^2 \approx M_W^2$, where nonperturbative effects are minimal. It is found that of the two current sets of parton distributions, those of Martin, Roberts and Stirling (MRS) are favored over the sets most recently produced by the CTEQ collaboration. The $W$ asymmetry data provide a stronger constraints on $d/u$ ratio than the recent measurements of $F_2^{\mu n}/F_2^{\mu p}$ which are limited by uncertainties originating from deutron corrections.Comment: to be published in PR

Limits on WWZWWZ and WWγWW\gamma couplings from WWWW and WZWZ production in pp‾p\overline{p} collisions at s=1.8\sqrt{s} = 1.8 TeV

Direct limits are set on $WWZ$ and $WW\gamma$ three-boson couplings in a search for $WW$ and $WZ$ production with high transverse momentum in $p\overline{p}$ collisions at $\sqrt{s} = 1.8$ TeV, using the Collider Detector at Fermilab. The results are in agreement with the SU(2) $\times$ U(1) model of electroweak interactions. Assuming Standard Model $WW\gamma$ coupling, the the limits are interpreted as direct evidence for a non-zero $WWZ$ coupling at subprocess energies near 500 GeV. Alternatively, assumiong identical $WWZ$ and $WW\gamma$ couplings, bounds $-0.11 < \kappa < 2.27$ and $-0.81 < \lambda < 0.84$ are obtained at $95\%$ CL for a form factor scale 1000 GeV.Comment: 16 pages, submitted to PRL, URL: http://www-cdf.fnal.gov/physics/pub95/cdf2951_vvprl.p

Z + {gamma} cross-section measurement, {sigma}*BR(Z + {gamma}), in the electron channel for p{bar p} collisions at {radical}s = 1.8 TeV, and limits for the ZZ{gamma} and Z{gamma}{gamma} anomalous couplings

The Z + {gamma} cross-section x branching ratio in the electron channel has been measured using the inclusive Z data sample from the CDF 1988--1989 collider run, for which the total integrated luminosity was 4.05 {plus_minus} 0.28 pb{sup {minus}1}. Two Z{gamma} candidates are observed from central photon events with {Delta}R/{sub {gamma}} > 0.7 and E{sub t}{sup {gamma}} > 5.0 GeV. From these events the {sigma} * BR(Z + {gamma}) is measured and compared with SM predictions: {sigma} * BR(Z + {gamma}){sub e} = 6.8{sub {minus}5.7}{sup +5.7}(stat + syst)pb {sigma} * BR(Z + {gamma})SM = 4.7{sub {minus}4.7}{sup +0.7}(stat + syst)pb. From this ZZ{sub {gamma}} cross section measurement limits on the Z{sub {gamma}{gamma}} and couplings for three different choices of compositeness scale {Lambda}{sub Z} are obtained. The experimental sensitivity to the h{sub 30}{sup Z,{gamma}}/h{sub 10}{sup Z,{gamma}} couplings is in the range of {Lambda}{sub Z} {approximately} 450--500 GeV and for the h{sub 40}{sup Z{gamma}}/h{sub 20}{sup Z,{gamma}} couplings {Lambda}{sub Z} {approximately} 300 GeV

OBSERVATION OF THE DECAY B(S)0-]J-PSI-PHI IN (P)OVER-BAR-P COLLISIONS AT ROOT-S = 1.8 TEV

none355This Letter reports the observation and mass measurement of fully reconstructed B(s)0 mesons through the decay chain B(s)0 --> J/psiphi, J/psi --> mu+mu-, phi --> K+K- using data obtained at the Collider Detector at Fermilab in ppBAR collisions at square-root s = 1.8 TeV. A signal of 14.0 +/- 4.7 events is observed. Comparison of the B(s)0 signal with the kinematically similar decays B+ --> J/psiK+ and B0 --> J/psiK*(892)0 is presented. The mass of the B(s)0 meson is determined to be 5383.3 +/- 4.5 (stat) +/- 5.0 (syst) MeV/c2.noneF. ABE;M. ALBROW;D. AMIDEI;C. ANWAYWIESE;G. APOLLINARI;H. ARETI;P. AUCHINCLOSS;F. AZFAR;P. AZZI;N.

MEASUREMENT OF THE RATIO SIGMA-B(W-]E-NU)/SIGMA-B(Z(0)-]E+E-) IN P(OVER-BAR)-P COLLISIONS AT ROOT-S=1.8-TEV

We present a measurement of the ratio sigmaB(W --> eupsilon)/sigmaB(Z0 --> e+e-) in ppBAR collisions at square-root s = 1.8 TeV. The data represent an integrated luminosity of 21.7 pb-1 from the 1992-1993 run of the Collider Detector at Fermilab. We find sigmaB(W --> eupsilon)/sigmaB(Z0 --> e+e-) = 10.90 +/- 0.32(stat) +/- 0.29(syst). From this value, we extract a value for the W width, GAMMA(W) = 2.064 +/- 0.061(stat) +/- 0.059(syst) GeV, and the branching ratio, GAMMA(W --> eupsilon)/GAMMA(W) = 0.1094 +/- 0.0033(stat) +/- 0.0031(syst), and we set a decay-mode-independent limit on the top quark mass m(top) > 62 GeV/c2 at the 95% C.L

MEASUREMENT OF THE POLARIZATION IN THE DECAYS B-D-]J/PSI-K-(ASTERISK-0) AND BS-]J/PSI-PHI

This Letter reports on measurements of the longitudinal polarization fractions in the decays B-d --> J/psi K*(0) and B-s --> J/psi phi using data collected with the Collider Detector at Fermilab. B-d mesons are reconstructed through the decay chain B-d --> J/psi K*(0), J/psi --> mu(+)mu(-), K*(0) --> K(+)phi(-). A sample of 65 +/- 10 B-d events is used to obtain a longitudinal polarization fraction of T-L/Gamma = 0.65 +/- 0.10(stat) +/- 0.04(syst). B-s mesons are reconstructed through the decay chain B-s --> J/psi phi, J/psi --> mu(+)mu(-), phi --> K+K-. A sample of 19 +/- 5 B-s events is used to obtain the result Gamma(L)/Gamma = 0.56 +/- 0.21(stat)-(+0.02)(0.04)(syst)

DIRECT MEASUREMENT OF THE W-BOSON WIDTH

This Letter describes a direct measurement of the W boson decay width, Γ(W), using the high-mass tail of the transverse mass spectrum of W→eν decays recorded by the Collider Detector at Fermilab. We findΓ(W)=2.11±0.28(stat)±0.16(syst) GeV and compare this direct measurement with indirect means of obtaining the width. © 1995 The American Physical Society
