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 κ fitted to the LHC data on the nuclear modification factor $${{R}_{{AA}}}$$. We find that the theoretical multiplicity dependence of the ratio $${{I}_{{pp}}}{\text{/}}\langle {{I}_{{pp}}}\rangle $$ for 5.02 TeV $$pp$$ collisions agrees reasonably with the recent preliminary ALICE data [1].
