Investigation of angular distributions in the interaction of cosmic-ray particles with a dense target and comparision with data of the large

The events registered in REC located in Tien-Shan mountain scientific station of cosmic rays at an altitude of 3340 m have been processed using the method of estimating probability density proposed at LHC. Total amount of registered events is 10 199, 462 events were selected of gamma ray families with n ≥ 4. Gamma ray families with short avalanches in the ionization calorimeter in further analysis are not included. The paper presents received results of twoparticle angular correlations over a wide range of pseudorapidities () and azimuth angle () and compared with data of the two-particle angular correlation on CMS detector in LHC.
