摘要
We study modification of the photon-tagged and inclusive jets in pp collisions at root s = 7 TeV due to mini-quark-gluon plasma which can be produced in high multiplicity events. We show that for underlying events with dN(ch)/d eta similar to 20-60 the medium effects lead to a considerable modification of the photon-tagged and inclusive jet fragmentation functions. For inclusive jets, the magnitude of the effect is surprisingly large. The effect is quite strong even for typical underlying events. We find that the spectrum of charged hadrons is suppressed by similar to 35%-40% at p(T) similar to 5-10 GeV.
