Measurement of the Forward-Backward Asymmetry in Bottom-Quark Pair Production Using Soft Muon
ثبت نشده
چکیده
We investigate the forward-backward asymmetry, AFB, in b-quark pair production in protonantiproton collision at √ s = 1.96 GeV with the CDF detector. The soft muon tag technique has been applied to identify bb̄ production. Using the full CDF data set (6.9 fb−1) we have obtained the integrated asymmetry at particle level of AFB= (1.2 ± 0.7)% for dijet invariant mass above 40 GeV/c. Dependence of AFB on dijet invariant mass has been retrieved.

Asymmetries in the angular distributions in the tt̄ system
Asymmetries in the pair production of top–antitop quarks in hadronic collisions have gained a lot of attention because the size of the effect exceeded the predictions based on the Standard Model (SM). To understand the basis for these predictions as well as the importance of this measurement and its experimental subtleties, it is instructive to review its historic predecessor — the asymmetry of...
متن کاملParity Violation in Bottom Quark Pair Production at Polarized Hadron Colliders
Parity violation induced by the chromo-anapole form factor of the bottom quark, generated from weak corrections, is studied in polarized hadron collisions. The forward-backward asymmetry in the bottom quark pair production at polarized pp and pp̄ colliders is evaluated in the Standard Model and in a Two Higgs Doublet Model to examine the effects of parity violation. In the models studied, promis...
متن کاملMeasurement of the Forward-Backward Charge Asymmetry in Top-Quark Pair Production in Proton-Antiproton Collisions at DØ
A measurement of the forward-backward charge asymmetry in top-antitop (tt̄) pair production in proton-antiproton (pp̄) collisions is presented. The asymmetry is measured for different jet multiplicities in the lepton+jets final state on 0.9 fb−1 of data collected by the DØ experiment at the Fermilab Tevatron Collider. The result is sensitive to new physics, which is demonstrated by setting an upp...
متن کاملMeasurement of the cross - section and forward - backward charge asymmetry for the b and c - quark in e + e − annihilation with inclusive muons at √ s = 58 GeV TOPAZ
We have studied inclusive muon events using all the data collected by the TOPAZ detector at √ s = 58GeV with an integrated luminosity of 273pb. From 1328 inclusive muon events, we measured the ratio Rqq̄ of the cross section for qq̄ production to the total hadronic cross section and forward-backward asymmetry AqF B for b and c quarks. The obtained results are Rbb̄ = 0.13 ± 0.02(stat) ± 0.01(syst),...
متن کاملLHC Predictions from a Tevatron Anomaly in the Top Quark Forward-Backward Asymmetry
We examine the implications of the recent CDF measurement of the top-quark forward-backward asymmetry, focusing on a scenario with a new color octet vector boson at 1-3 TeV. We study several models, as well as a general effective field theory, and determine the parameter space which provides the best simultaneous fit to the CDF asymmetry, the Tevatron top pair production cross section, and the ...
