Medium effects for hadron-tagged jets in proton-proton collisions

Abstract

We study the medium modification factor $I_{pp}$ within the light-cone path integral approach to induced gluon emission. We use parametrization of the running coupling ${\alpha }_s(Q,T)$ which has a plateau around $Q\sim \kappa T$. We calculate $I_{pp}$ with no free parameters using $\kappa$ fitted to the LHC data on the nuclear modification factor $R_{AA}$. We find that the theoretical multiplicity dependence of the ratio $I_{pp}/⟨I_{pp}⟩$ for $5.02$ TeV $pp$ collisions agrees reasonably with the recent preliminary data from ALICE [1].
