Abstract

We analyze high multiplicity proton-proton (pp) collision data in the framework of the String Percolation Model (SPM) that has been successful in describing several phenomena of multiparticle production, including the signatures of recent discovery of strongly interacting partonic matter, the Quark Gluon Plasma (QGP), in relativistic heavy-ion collisions. Our study in terms of the ratio of shear viscosity and entropy density (η/s) and the (LQCD) predicted signature of QCD change of phase, in terms of effective number of degrees of freedom (ε/T⁴), reiterates the possibility of strongly interacting collective medium in these events.
