Measurement of t-channel production of single top quarks and antiquarks in pp collisions at 13 TeV using the full ATLAS Run 2 data sample
Original language description
The production of single top quarks and top antiquarks via the t-channel exchange of a virtual W boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC using 140 fb−1−1 of ATLAS data. The total cross-sections are determined to be σ(tq)=137−8+8σ(tq)=137−8+8 pb and σ(t‾q)=84−5+6σ(tq)=84−5+6 pb for top-quark and top-antiquark production, respectively. The combined cross-section is found to be σ(tq+t‾q)=221−13+13σ(tq+tq)=221−13+13 pb and the cross-section ratio is Rt=σ(tq)/σ(t‾q)=1.636−0.034+0.036Rt=σ(tq)/σ(tq)=1.636−0.034+0.036. The predictions at next-to-next-to-leading-order in quantum chromodynamics are in good agreement with these measurements. The predicted value of Rtt using different sets of parton distribution functions is compared with the measured value, demonstrating the potential to further constrain the functions when using this result in global fits.
