Inclusive top cross sections in ATLAS

The ATLAS collaboration at the LHC has published inclusive cross-section measurements for the single-top and t\overline{t} t t ¯ production modes at center-of-mass energies of \sqrt{s} = 5.02, 8.16 s = 5.02 , 8.16 , 13 13 , and 13.6 13.6 TeV. Single-top measurements are conducted in the t t -channel and tW t W channel. In addition to the nominal cross-section measurements, various measurements of other interesting observables such as the V_{tb} V t b element of the Cabibbo Kobayashi Maskawa (CKM) quark-mixing matrix, the ratio of the inclusive cross-sections between tq t q and t\overline{q} t q ¯ , the ratio of inclusive cross-sections between t\overline{t} t t ¯ and Z→ \ell\ell Z → ℓ ℓ , and the nuclear modification factor (defined as the ratio of the inclusive t\overline{t} t t ¯ cross section in heavy-ion collisions to the inclusive t\overline{t} t t ¯ cross-section in pp p p collisions) are also reported. These results are compared to their corresponding SM predictions, calculated at (N)NLO in QCD. All results are in good agreement with SM predictions.
