Description
In high energy nucleon-nucleon and heavy-ion (HI) collisions, the heavy quarks (charm and beauty) are produced at the very early stages of the collisions due to their large masses ($m_{c}\approx$ 1.29 GeV/$\it{c}^{2}$ and $m_{b}\approx$ 4.19 GeV/$\it{c}^{2}$). These heavy quark productions are mainly from hard parton-parton scattering with large momentum transfer ($Q^{2}$). The heavy quarks are produced much before the formation of the deconfined state of quarks and gluons called Quark-Gluon Plasma (QGP) at extremely high temperature and/or energy density in ultra-relativistic HI collision. After the production of heavy-quarks, they interact and pass through the QGP medium and hence experience a full evolution of the medium formed in HI collisions. Hence, the measurement of heavy quarks is very important probe to study the properties of QGP in HI collisions and provide a stringent test of perturbative QCD (pQCD) calculation over a wide range of transverse momentum ($p_{T}$). The measurement of heavy quarks in pp collisions serve as a baseline study for the same measurement in HI collisions.
After the discovery of the features of HI collisions such as ridge like effect and strangeness enhancement in high multiplicity pp events at LHC, the physics community started to look for any thermalised medium formation even in small colliding systems. Traditionally, any thermalised medium is not expected to be formed in small systems like proton-proton (pp) and proton-ion (pA) collisions. Here we would like to present the study of Heavy Flavour decay Muons (HFM) at forward rapidity ($2.5
