| 英文摘要 | Measurements of jet activity in top-quark pair events produced in proton-proton collisions are presented, using 3.2 fb of pp collision data at a centre-of-mass energy of 13 tev collected by the atlas experiment at the large hadron collider. events are chosen by requiring an opposite-charge pair and two b-tagged jets in the final state. the normalised differential cross-sections of top-quark pair production are presented as functions of additional-jet multiplicity and transverse momentum, . the fraction of signal events that do not contain additional jet activity in a given rapidity region, the gap fraction, is measured as a function of the threshold for additional jets, and is also presented for different invariant mass regions of the system. all measurements are corrected for detector effects and presented as particle-level distributions compared to predictions with different theoretical approaches for qcd radiation. while the kinematics of the jets from top-quark decays are described well, the generators show differing levels of agreement with the measurements of observables that depend on the production of additional jets. |
