Photons are radiated during all stages of heavy-ion collisions, including from the hot and dense quark-gluon plasma (QGP). In this talk, we consider the polarization of these QGP photons. The polarization, albeit difficult to measure, gives detailed information about how the anisotropy of the QGP medium evolves and thus how the medium isotropizes during the initial stages of collisions. We...
Various features of quantum chromodynamics (QCD) are an essential part of the phenomenology of the events at hadron colliders, such as the LHC, including soft and non-perturbative features. In order to constrain the parameters of models of soft QCD, diverse measurements are provided by the ALICE, ATLAS and CMS collaborations. Particle production mechanism including the underlying event...
We evaluate the longitudinal or (chromo-)electric Yang-Mills gluon propagator in the recently proposed center-symmetric Landau gauge at finite temperature. To model the effect of the Gribov copies in the infrared, we use the Curci-Ferrari model which, in turn, allows us to rely on perturbative calculations. At one-loop order in the SU(2) case, the so-obtained longitudinal gluon propagator...
This talk shows the studies about open heavy flavor, quarkonia, Z and W in PbPb collisions in ALICE, ATLAS, LHCb, CMS experiments.
