چکیده
Detailed measurements of t-channel single top-quark production are presented. They use 20.2 fb[Formula: see text] of data collected by the ATLAS experiment in proton-proton collisions at a centre-of-mass energy of 8 TeV at the LHC. Total, fiducial and differential cross-sections are measured for both top-quark and top-antiquark production. The fiducial cross-section is measured with a precision of 5.8% (top quark) and 7.8% (top antiquark), respectively. The total cross-sections are measured to be [Formula: see text] for top-quark production and [Formula: see text] for top-antiquark production, in agreement with the Standard Model prediction. In addition, the ratio of top-quark to top-antiquark production cross-sections is determined to be [Formula: see text]. The differential cross-sections as a function of the transverse momentum and rapidity of both the top quark and the top antiquark are measured at both the parton and particle levels. The transverse momentum and rapidity differential cross-sections of the accompanying jet from the t-channel scattering are measured at particle level. All measurements are compared to various Monte Carlo predictions as well as to fixed-order QCD calculations where available.

متن کاملTop quark production in the ATLAS detector of the LHC
Top quark has been re-discovered at LHC in 2010 by the CMS and the ATLAS experiments. The top quark is the heaviest known elementary particle, and its properties might offer a hint of physics beyond the Standard Model. Therefore, it is interesting to measure them as precisely as possible. We present a summary of a variety of measurements relating to the top quark production in pp collisions wit...

The measurement of the t ¯ t production cross-section in the single-lepton channel in pp collisions at a centre-of-mass energy √ s =7 TeV is presented. The analysis is based on a multivariate discriminant distribution in 3, 4 and ≥ 5 jet bins using three kinematic variables and b-tagging information. With a data sample of about 35 pb −1 recorded by ATLAS in 2010 the inclusive top quark producti...

A search is performed for top-quark pairs (tt̄) produced together with a photon (γ) with transverse energy greater than 20 GeV using a sample of tt̄ candidate events in final states with jets, missing transverse momentum, and one isolated electron or muon. The data set used corresponds to an integrated luminosity of 4.59 fb−1 of proton-proton collisions at a center-of-mass energy of 7 TeV recorde...
