Description
We study jet quenching in $pp$ and $pA$ collisions in the scenario with
formation of a mini quark-gluon plasma.
We find a significant suppression effect. For light hadrons
at $p_{T}\sim 10$ GeV we obtained the reduction of the spectra
by $\sim [20-30,25-35,30-40]$% in $pp$ collisions at
$\sqrt{s}=[0.2, 2.76,7]$ TeV.
We also give predictions for modification of the photon-tagged
and inclusive jet fragmentation functions in high multiplicity $pp$
events. We show that for underlying $pp$ events with
$dN_{ch}/d\eta\sim 20-60$ the medium effects lead to
a considerable modification of the jet fragmentation functions.
