The ALICE Collaboration focuses on studying the matter at extremely high temperature and density created by heavy-ion collisions in the laboratory. This state of matter is called quark-gluon plasma (QGP) and is made of deconfined quarks and gluons. The QGP is thought to exist for the first few microseconds after the Big Bang. During the collision, many particles are produced, in particular the...

Heavy (beauty and charm) quarks are very valuable probes of the quark-gluon plasma created in heavy ion collisions, because they experience the whole evolution of the medium. They can also help understanding the dynamics of hadronization, and how they are affected by the interaction with the medium. In this context, the B_c meson is an interesting and new probe, that could both give new...

108. Quarkonium anisotropic flow in Pb-Pb collisions with ALICE

ALICE experiment at LHC studies through ultra-relativistic heavy ion collisions, a deconfined state of matter, the Quark Gluon Plasma (QGP). This state raises many questions about mechanisms of strong interaction and the cohesion of matter. Moreover, QGP is an extremely hot and dense state that behaves more like a nearly ideal, strongly interacting fluid and it can represents the universe at...

127. Measurement of an excess in the yield of J/ψ at very low pT in Pb-Pb collisions at 5.02 TeV with ALICE

In 2015, the ALICE collaboration reported the first excess in the yield of $J/\psi$ at very low transverse momentum ($p_T<0.3\ GeV/c$) in the forward rapidity region ($ 2.5 < y <4 $) in peripheral Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV at the CERN LHC. [1] The coherent photo-production was proposed as the potential underlying physics mechanism. This mechanism is the main responsible...

103. Weak boson production in p-Pb at 8.16 TeV with ALICE

Guillaume Taillepied (LPC Clermont)

The measurement of the Z and W production cross sections in heavy-ion collisions allow to probe the internal structure of the nucleus and constrain the nuclear Partonic Distribution Functions. The work presented here is based on data from proton$-$lead collisions at $\sqrt{s_{_{\rm NN}}}$ = 8.16 TeV recorded with ALICE.
