The production of charmonium states (for instance J/$\psi$ and $\psi(2S)$) is one of the probes studied to investigate the properties of the Quark-Gluon Plasma (QGP) formed in high-energy heavy-ion collisions. Indeed, the presence of a deconfined medium should modify the charmonium production yield, due to the color screening of the charm quark anti-quark potential. Such a suppression was...
Charm quarks are predominantly produced in the early stages of the heavy-ion
collisions via hard scattering because of
their high mass. Thus, they experience the entire evolution of the Quark-Gluon Plasma
created in such collisions. Compared to light quarks,
charm quarks thermalize more slowly. The open
charm hadrons present, therefore, a unique probe to the properties of
the hot and...
Charmonium production in hadronic collisions is a complex process involving both hard scales, i.e. the production of charm-anticharm quark pairs in initial hard collisions, and soft scales, i.e. the subsequent formation of a bound charmonium state. The former can be addressed by perturbative Quantum ChromoDynamics (QCD), whereas the latter fall into the non-perturbative regime of QCD....
Jets are a fundamental feature of high-energy particle interactions.
They result from the fragmentation of hard-scattered partons,
a key process of Quantum Chromodynamics (QCD).
In particular, the production and the internal properties of heavy-flavor jets
in pp collisions are not yet satisfactorily described by neither analytical nor
phenomenological approaches to QCD. Measurements...
The Psi prime (Psi(2S)) meson yield in PbPb collisions is of particular interest when compared to the J/psi meson. A variety of effects modify the charmonium production in PbPb collisions with respect to pp collisions, including melting in the quark gluon plasma and statistical recombination, which can have a different impact on the J/psi and the Psi(2S) mesons. Using pp and PbPb data at...

The ALICE experiment at LHC is dedicated to studies of the quark-gluon plasma (QGP) state, which is created in heavy-ion collisions. Neutral mesons are excellent probes for QGP formation studies. The medium-induced energy loss of particles can be investigated...
