Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

Abstract The Large Hadron Collider at CERN, delivering proton–proton collisions at much
higher energies and far higher luminosities than previous machines, has enabled a …

A bstract The first measurement of the top quark pair (\(\textrm {t}\overline {\textrm {t}}\))
production cross section in proton-proton collisions at\(\sqrt {s}\)= 13. 6 TeV is presented …

A bstract An intuitive definition of the partonic flavor of a jet in quantum chromodynamics is
often only well-defined in the deep ultraviolet, where the strong force becomes a free theory …

This paper presents a measurement of the production cross-section of a Z boson in
association with b-or c-jets, in proton–proton collisions at s= 13 TeV with the ATLAS …

We present a methodology to streamline implementation of massive-quark radiative
contributions in calculations with a variable number of active partons in proton-proton …

A bstract We propose a new strategy to probe the Z boson couplings to bottom and charm
quarks at the LHC. In this work we mainly focus on the case of bottom quarks. Here, the Z …

We consider the production of a Z boson decaying to leptons in association with a bottom-
quark pair in hadronic collisions. For the first time, we compute predictions at next-to-next-to …

A search for the central exclusive production of top quark-antiquark pairs (tt⎯⎯) is performed
for the first time using proton-tagged events in proton-proton collisions at the LHC at a centre …

This paper presents a measurement of the production cross-section of a Z boson in
association with b-or c-jets, in proton–proton collisions at√ s= 13 TeV with the ATLAS …
