Abstract

Identical neutral kaon pair correlations are measured in √s = 7 TeV pp collisions in the ALICE experiment. One-dimensional K0sK0s correlation functions in terms of the invariant momentum difference of kaon pairs are formed in two multiplicity and two transverse momentum ranges. The femtoscopic parameters for the radius and correlation strength of the kaon source are extracted. The fit includes quantum statistics and final-state interactions of the a0/f0 resonance. K0sK0s correlations show an increase in radius for increasing multiplicity and a slight decrease in radius for increasing transverse mass, mT, as seen in ππ correlations in pp collisions and in heavy-ion collisions. Transverse mass scaling is observed between the K0sK0s and ππ radii. Also, the first observation is made of the decay of the f2(1525) meson into the K0sK0s channel in pp collisions.
