Effect of differential cross section in Breit–Wheeler pair production

The effect of the Higgs boson on the threshold cross-section in W -pair production

We investigate the uncertainty induced by the Higgs-boson mass on the determination of mW from the LEP-2 run near the threshold for W -pair production. For a light Higgs boson the Yukawa interaction between the two slowly-moving W bosons gives rise to a correction of close to 1% to the total cross-section. This corresponds to a 15 MeV shift in the deduced W mass for a Higgs-boson mass of 60 GeV...

Top Quark Pair Production Cross Section at the Tevatron

Top quark pair production cross section has been measured at the Tevatron by CDF and DØ collaborations using different channels and methods, in order to test standard model predictions, and to search for new physics hints affecting the tt̄ production mechanism or decay. Measurements are carried out with an integrated luminosity of 1.0 to 2.0 fb, and are found to be consistent with standard model...

Differential Cross Sections for Top-pair and Single-top Production

Measurement of the differential cross section for top quark pair production in pp collisions at sqrt(s) = 8 TeV

The normalized differential cross section for top quark pair (tt) production is measured in pp collisions at a centre-of-mass energy of 8 TeV at the CERN LHC using the CMS detector in data corresponding to an integrated luminosity of 19.7 fb−1. The measurements are performed in the lepton+jets (e/μ+jets) and in the dilepton (e+e−, μ+μ−, and e±μ∓) decay channels. The tt cross section is measured...

Top Quark Pair Production Cross Section in the Lepton+Jets Final State at DØ

Preliminary and published results obtained by the DØ Collaboration on the top quark pair production cross-section in p ¯ p collisions at a center-of-mass energy of ¡ s ¢ 1£ 96 TeV are presented. The measurements are obtained using the lepton+jets final states with two methods : in the first one, signal is discriminated from background using event kinematics and in the other method signal events...
