Title: Exploring the Property of Strongly-Interacting Matter via Hard Probes with ALICE Detectors

Abstract:The LHC heavy-ion physics program aims at investigating the properties of strongly-interacting matter in extreme conditions of temperature and energy density where the formation of the Quark Gluon Plasma (QGP) is expected. The heavy-ion physics program requires also the study of proton-proton (pp) and proton-nucleus collisions. Besides providing the essential baseline for measurements in proton-nucleus and nucleus-nucleus collisions, pp collisions are of great interest, also in their own right, since they provide a sensitive test of quantum chromodynamics. The study of proton-nucleus collisions is used to disentangle experimental observations arising due to the hot and dense medium from those occurring due to cold nuclear matter effects such as modifications of the parton distribution functions in the nucleus, gluon saturation, kT-broadening.Among the most promising observables, the hard probes (heavy flavours and jets) are especially relevant since they provide an essential probe of the earliest stages of the collision. The studies of the hard probe productions in different colliding systems Pb-Pb, p-Pb and pp play a central role in extracting the physical properties, such as density and temperature, of the QGP. Moreover, the measurements of identified particles in jets provide an in-depth sensitivity to the flavor dependence of the jet fragmentation and hadronization processes.ALICE (A Large Ion Collider Experiment) is designed and optimized to study ultra-relativistic heavy-ion collisions at the LHC. An overview of recent measurements on open heavy-flavour and jet measurements in Pb-Pb, p-Pb and pp collisions with ALICE will be presented.
