Formation time dependence of femtoscopic $\pi \pi$ correlations in p+p collisions at $\sqrt{s_{NN}}$=7 TeV

Abstract

We investigate femtoscopic $\pi \pi$ correlations using the UrQMD approach combined with a correlation afterburner. The dependence of $\pi \pi$ correlations on the charged particle multiplicity and formation time in p+p collisions at $\sqrt{s_{NN}}$= 7 TeV is explored and compared to present ALICE data. The data allows to constrain the formation time in the string fragmentation to ${\tau }_f\le 0.8$ fm/c.
