Correlation femtoscopy of Λ hyperons in the SELEX experiment

Study of the correlations of two identical particles with a small relative difference in their 4-momenta can provide information on the space-time behavior of a source and the shape of the potential between the particles. Our study of correlations is based on the SELEX experimental data. From a set of events involving Λ pairs, we selected the approximately ∼2600 such events with the best kinematical parameters, on the basis of which the preliminary results from our analysis of ΛΛ system correlations are presented.
