Beam and target dependencies of two-kaon femtoscopic correlations in SELEX

Abstract

Abstract. The space and time extents of the particle emitting source created in collisions of particles with nuclei can be measured using a correlation femtoscopy method. In this paper we show the preliminary measurements of K ± K ± correlation functions in 600 GeV/c Σ − , π − and 540 GeV/c p interactions with carbon and copper nuclei. The one-dimensional correlation functions are parameterized by a Gaussian form. The dependencies of the charged kaon emitting source radii on the different h+A collisions are presented.
