Induced gluon radiation which acccompanies hard parton muddling through medium results in quenching of the yield of large-Pt hadrons. In the LHC environment, the quenching factors can be reliably predicted from 'first principles', and, due to a strong bias effect, have little to do with the so-called average energy loss.
