Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the W± → l±[nu] and Z → l+l- production cross sections (where l± = e±, [mu]± ) in proton-proton collisions at √s = 13 TeV are presented using data recorded by the ATLAS experiment at the Large Hadron Collider, corresponding to a total integrated luminosity of 81 pb-1. The total inclusive W±-boson production cross sections times the single-lepton-flavour branching ratios are [sigma]Wtot+ =11.83 ± 0.02 (stat)±0.32 (sys)±0.25 (lumi) nb and [sigma]W-tot=8.79±0.02 (stat)±0.24 (sys)±0.18 (lumi) nb for W+ and W- , respectively.
Download or read book Measurement of the Total and Differential Inclusive mathrm B Hadron Cross Sections in Pp Collisions at sqrt s written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The total and differential cross sections for inclusive production of $\mathrm{B}^{+}$ hadrons are measured as a function of the $\mathrm{B}^{+}$ transverse momentum $p_{\mathrm{T}}^\mathrm{B}$ and rapidity $y^\mathrm{B}$ in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 49.4 pb$^{-1}$. The measurement uses the exclusive decay channel $\mathrm{B}^{+} \to \mathrm{J}/\psi \mathrm{K}^{+}$, with $\mathrm{J}/\psi$ mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties.

Available in PDF, EPUB and Kindle. Book excerpt: The {bar p}p differential elastic scattering cross section was measured at √{bar s} = 1800 GeV, using an improved accelerator luminosity determination and CDF small angle data in the range of 0.05 ≤ t ≤ 0.2(GeV/c)2. By extrapolating the differential cross sections to t=0 and using the optical theorem we obtain a total cross section of [sigma]{sub tot}({bar p}p) = 72.0 {plus minus} 3.6 mb. This result is preliminary in the sense that we expect to further reduce the systematic error on the optical point. 9 refs., 8 figs.

Available in PDF, EPUB and Kindle. Book excerpt: The CDF collaboration has measured the differential elastic cross section d?{sub el}/dt, the single diffraction dissociation double differential cross section d2?{sub sd}/dM2dt and the total inelastic cross section for antiproton-proton collisions at center of mass energies √s = 546 and 1,800 GeV. Data for this measurement have been collected in short dedicated runs during the 1988--1989 data taking period of CDF. The elastic scattering slope is 15.28 ± 0.58 (16.98 ± 0.25) GeV−2 at √s = 546 (1,800) GeV. Using the luminosity independent method (1 +?2)?{sub T} is measured to be 62.64 ± 0.95 (81.83 ± 2.29) mb at √s = 546 (1,800) GeV.

Available in PDF, EPUB and Kindle. Book excerpt: A measurement of the W boson pair production cross section in proton-proton collisions at [arrow]"s = 8 TeV is presented. The data we collected with the CMS detector at the LHC correspond to an integrated luminosity of 19.4 fb-1 . The W+W- candidates are selected from events with two charged leptons, electrons or muons, and large missing transverse energy. The measured W+W- cross section is 60.1 " 0.9 (stat) " 3.2 (exp) " 3.1 (theo) " 1.6 (lumi) pb = 60.1 " 4.8 pb, consistent with the standard model prediction. The W+W-cross sections are also measured in two different fiducial phase space regions. The normalized differential cross section is measured as a function of kinematic variables of the final-state charged leptons and compared with several perturbative QCD predictions. Limits on anomalous gauge couplings associated with dimension-six operators are also given in the framework of an effective field theory. Finally, the corresponding 95% confidence level intervals are -5.7

Available in PDF, EPUB and Kindle. Book excerpt: The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying [tau] lepton from the process $t\bar{t}$ to (l[nu]l) ([tau][nu][tau]) $b\bar{b}$, where l = e, [mu]. The data sample corresponds to an integrated luminosity of 19.6 fb-1 collected with the CMS detector in proton-proton collisions at $\sqrt{s}$ =8 TeV. The measured cross section [sigma]$t\bar{t}$ = 257 ± 3 (stat) ± 24 (syst) ± 7 (lumi) pb, assuming a top-quark mass of 172.5 GeV, is consistent with the standard model prediction.
