With the high collision energies at the LHC, the contributions to particle production from hard-QCD processes increase, but it remains dominated by soft-QCD processes. Such processes challenge the theoretical models, since they are…
Heavy-flavour hadrons, containing open or hidden charm and beauty flavours, are considered as hard probes of the quark-gluon plasma (QGP), which is a hot and dense phase state of quantum chromodynamics (QCD) matter. Production of heavy…
Particle production at LHC energies involves the interplay of hard (perturbative) and soft (non-perturbative) QCD processes. Global observables, such as the charged-particle multiplicity, are related to the initial geometry and the energy…
