Measurements of the production cross-section for a ๐ boson in association with ๐- or ๐-jets in protonโproton collisions at โs = 13 TeV with the ATLAS detector
This paper presents a measurement of the production cross-section of a ๐ boson in association with ๐- or ๐-jets, in protonโproton collisions at โs = 13 TeV with the ATLAS experiment at the Large Hadron Collider using data corresponding to an integrated luminosity of 140 fbโปยน. Inclusive and differential cross-sections are measured for events containing a Z boson decaying into electrons or muons and produced in association with at least one ๐-jet, at least one ๐-jet, or at least two ๐-jets with transverse momentum ๐T > 20 GeV and rapidity |y| < 2.5.
Predictions from several Monte Carlo generators based on next-to-leading-order matrix elements interfaced with a parton-shower simulation, with different choices of flavour schemes for initial-state partons, are compared with the measured cross-sections. The results are also compared with novel predictions, based on infrared and collinear safe jet flavour dressing algorithms. Selected ๐+ โฅ 1 ๐-jet observables, optimized for sensitivity to intrinsic-charm, are compared with benchmark models with different intrinsic-charm fractions.
