Measurement of jets and photons with the ALICE experiment at the LHC

Jets and direct photons are used to probe the formation and the properties ofthe Quark-Gluon Plasma (QGP) by the ALICE Collaboration. The results shown herewill present the measurements obtained from Pb–Pb and p–Pb collisions. It isobserved that in Pb–Pb collisions jets are collimated and hadron yie...

description Jets and direct photons are used to probe the formation and the properties ofthe Quark-Gluon Plasma (QGP) by the ALICE Collaboration. The results shown herewill present the measurements obtained from Pb–Pb and p–Pb collisions. It isobserved that in Pb–Pb collisions jets are collimated and hadron yields (π 0 andη) at high transverse momentum undergo strong suppression due to the interactionof the patrons with the QGP. On the other hand, photons do not show anysuppression in this region, and, in addition, an excess attributed to a thermalemission is observed at low transverse momentum. No hints of mediummodifications are observed for the p–Pb results, for which a jet quenching limitof −0.4 GeV/c is calculated.

The results shown here will present the measurements obtained from Pb$-$Pb and p$-$Pb collisions. It is observed that in Pb$-$Pb collisions jets are collimated and hadron yields ($\pi^{0}$ and $\eta$) at high transverse momentum undergo strong suppression due to the interaction of the patrons with the QGP. On the other hand, photons do not show any suppression in this region, and, in addition, an excess attributed to a thermal emission is observed at low transverse momentum. No hints of medium modifications are observed for the p$-$Pb results, for which a jet quenching limit of $-$0.4 GeV/$c$ is calculated.arXiv:1805.09089oai:cds.cern.ch:26270502018
