Description
Recently, many results suggesting the production of Quark-Gluon Plasma (QGP) in high multiplicity events in small collision systems have been presented. These results were reported with surprise and have been a topic of intense discussion.
The purpose of the analysis presented in this talk is to look for the possibility of QGP formation in small collision systems through the measurement of low-mass vector mesons ($\rho$, $\omega$, $\phi$) decaying in the lepton pair channel. The analysis focuses on forward-rapidity muons instead of mid-rapidity electrons since the ALICE muon tracking system at forward rapidity allows for high-purity muon identification and momentum measurement to low transverse momentum. In addition, thanks to a dedicated muon pair trigger, it has been possible to enhance efficiently the sample of muon pairs.
This presentation will report the multiplicity and transverse momentum dependence of the low-mass vector meson production in pp collisions at √s = 13 TeV with full LHC-Run2 (2015-2018) data.
