Femtoscopic two-particle correlation measurements with the ALICE experiment at the LHCSebastian Huber1, •Jorge Mercado2, and Dariusz Miśkowiec11GSI Helmholtzzentrum für Schwerionenforschung GmbH, 64291 Darmstadt. — 2Physikalisches Institut der Universität Heidelberg, 69120 Heidelberg.

Femtoscopy is unique among all analysis techniques utilized in subatomic collision experiments as it directly addresses the space-time structure of the evolving system at the femto scale.

ALICE (A Large Ion Collider Experiment) is the experiment at the CERN Large Hadron Collider (LHC) dedicated to study high-energy nuclear collisions that will also exploit the proton–proton physics program with wide phase-space coverage and good resolution. We present the first femtoscopic analysis of two-particle correlations in p+p collisions at √s=900 GeV, measured with ALICE during its commissioning run in December 2009. Preliminary source dimensions are estimated from two-particle correlation functions, C(Qinv), constructed using these measurements.
