The transition from quarks to hadrons is a fundamental process in nature that can be studied at colliders. Given their mass of the GeV scale, charm and beauty quarks are mainly produced in the hard scattering processes occurring in the early stages of the hadronic collisions. Their production at the hadronization time is negligible, differently from light quarks. Thus, heavy quarks are used as...
The main goal of the ALICE experiment is to study the physics of strongly interacting matter, including the properties of the quark-gluon plasma (QGP). The enhanced production of strange hadrons with respect to non-strange hadrons was historically considered as one of the signatures of QGP formation during the evolution of the system created in heavy-ion collisions. The excellent tracking and...
It is well-established that high-multiplicity pp and p–Pb collisions exhibit a collective-like behaviour and signatures, like the strangeness enhancement and the ridge behaviors, that were commonly attributed to the formation of the Quark-Gluon Plasma. In this contribution, the similarity between small and large collision systems will be explored by studying the underlying event (UE)...
The energy densities reached in high-energy hadronic collisions at the LHC allow significant production of light (anti)nuclei.
Their production yields have been measured as a function of transverse momentum and charged-particle multiplicity in proton-proton, proton-lead and lead-lead collisions and at different center-of-mass energies by ALICE. One of the most interesting results obtained...
The enhanced production of strange hadrons in heavy-ion collisions relative to that in pp collisions was historically considered as one of the signatures of the formation of a deconfined quark-gluon plasma. At the LHC, recent measurements in pp and p-Pb collisions showed that the production of strange hadrons relative to pions increases with the charged particle multiplicity in the event, a...
