Nuclear modification factor for light and heavy flavors within pQCD and recent data from the LHC

Abstract: We examine the flavor dependence of the nuclear modification factor R AA in the pQCD calculations at LHC energies. The computations are performed accounting for radiative and collisional parton energy loss with running coupling constant. Our results show that the recent LHC data on the R AA for charged hadrons, D-mesons and non-photonic electrons agree reasonably with the pQCD picture of the parton energy loss with the dominating contribution from the radiative mechanism.1. The parton energy loss in the quark-… Show more

“…We confirm previous results pointing to the need to reduce of the jet-medium coupling from LHC to RHIC [26][27][28][29][30][31][32][33][34][35][36][37][38], with a jet-medium coupling κ LHC ≈ 0.5 κ RHIC that negates most of the increase of the jet-energy loss as expected from the factor of ∼ 2 increase of the QGP density at LHC relative to RHIC.…”

“…Besides that, we also study two models with a jet-medium coupling that either depends on the azimuth [39] or drops exponentially for large temperates. We consider a weaker κ LHC < κ RHIC coupling at LHC energies for the pQCD-like jet-energy loss prescriptions [26][27][28][29][30][31][32][33][34][35][36]39]. [26][27][28][29][30][31] without energy loss fluctuations, i.e., ζ −1 = 1.…”

“…As in [18][19][20][21] we evaluate radiative and collisional energy loss with running α s frozen at some value α f r s at low momenta. For gluon emission in vacuum a reasonable choice is α f r s ≈ 0.7 [25].…”

“…A number of theoretical calculations and Monte-Carlo simulations were attempted to reproduce some of basic features of jet quenching pattern at LHC (dijet and photon+jet imbalance, nuclear modification factors for jets and highp T hadrons), and to extract in such a way information as regards medium properties and partonic energy loss mechanisms [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. The observable that allows for a more precise comparison between the data and theoretical models of jet quenching to be done is the internal jet structure.…”
