Název v původním jazyce

Measurement of double-differential charged-current Drell-Yan cross-sections at high transverse masses in pp collisions at √s=13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

This paper presents a first measurement of the cross-section for the charged-current Drell-Yan process pp → W± → ℓ±ν above the resonance region, where ℓ is an electron or muon. The measurement is performed for transverse masses, mTWmTW​, between 200 GeV and 5000 GeV, using a sample of 140 fb−1 of pp collision data at a centre-of-mass energy of √s ​= 13 TeV collected by the ATLAS detector at the LHC during 2015–2018. The data are presented single differentially in transverse mass and double differentially in transverse mass and absolute lepton pseudorapidity. A test of lepton flavour universality shows no significant deviations from the Standard Model. The electron and muon channel measurements are combined to achieve a total experimental precision of 3% at low mTWmTW​. The single- and double differential W-boson charge asymmetries are evaluated from the measurements.
