Parallel Session IV: Quarkonia Production (I)
- Feng Liu (Central China Normal University)
The discovery of the J/$\psi$ meson opened the door to studying the heavy quark-antiquark system. This not only provides valuable knowledge for our understanding of Quantum Chromodynamics (QCD), but also plays an important role as a standard candle for discovering new physics. Quark Gluon Plasma (QGP) is a new phase of matter which surprisingly behaves like a perfect fluid, and it can be...
The ALICE experiment is dedicated to the study of the Quark-Gluon Plasma (QGP), a state of matter where, due to high temperature and energy density, quarks and gluons are deconfined.
One of the probes studied to investigate this state of matter is the production of charmonium states, such as the J/$\psi$ and the $\psi$(2S). Indeed, the presence of the QGP is expected to modify the...
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. Additional effects, like modification of nPDFs, initial-state energy loss and nuclear break-up, all probed also in pPb collisions, can affect the...
The in-medium suppression of heavy quarkonia production in heavy-ion collisions, with respect to proton-proton collisions, serves as a sensitive probe for studying the QGP. A full assessment of the suppression requires understanding effects present in the hot and dense medium in the A-A collisions as well as cold nuclear effects in the small-sized p+A collision. Based on proton-lead collision...
