Abstract

The study is dedicated to the multiplicity of momentum and angular characteristics of protons formed in nC-collisions at a pulse of 4.2 GeV/c. The experimental results on the formation of Δ0 isobars in nC-collisions at 4.2 GeV/c are presented for the first time. Experimental and normalised background distribution of the effective mass for protons and π−-mesons was obtained. This study is a follow-up to prior research. It explores various kinematic characteristics of π‒-mesons formed in nC-collisions at 4.2 GeV/c. The data obtained are compared with the experimental data obtained for pA interactions at the same energy. The experimental material used in this work was obtained using a 2-meter propane bubble chamber of the JINR LHE irradiated with beams of proton, deuteron and helium-4 nuclei at a pulse of 4.2 GeV/c per nucleon at the Dubna Synchrophasotron and consists of 6736 pC, 7071 dC and 11974 4HeC events. Negative π mesons are identified visually by the charge sign only.
