Abstract: (arXiv)

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 \leq 0.8

fm/c.

Note:
