Charged kaon femtoscopic correlations in pp collisions at $\sqrt{s}=7$ TeV

Abstract : Correlations of two charged identical kaons (Kch Kch) are measured in pp collisions at sqrt{s}=7 TeV by the ALICE experiment at the Large Hadron Collider (LHC). One-dimensional Kch Kch correlation functions are constructed in three multiplicity and four transverse momentum ranges. The Kch Kch femtoscopic source parameters R and lambda are extracted. The Kch Kch correlations show a slight increase of femtoscopic radii with increasing multiplicity and a slight decrease of radii with increasing transverse momentum. These trends are similar to the ones observed for pi pi and Ks0 Ks0 correlations in pp and heavy-ion collisions. However, the observed one dimensional correlation radii for charged kaons are larger at high multiplicities than those for pions in contrast to what was observed in heavy-ion collisions at RHIC.
