Abstract
AbstractData on the production of positively charged particles emitted at an angle of 40$${}^{\circ}$$ (in the laboratory frame) with transverse momenta of up to 2.7 GeV$$/c$$ in the interaction of 50-GeV$$/c$$ protons with carbon, aluminum, copper, and tungsten nuclear targets are presented. Particular attention is given to studying the production of light nuclear fragments, such as deuterons ($$d$$) and tritons ($$t$$). An analysis of data on $$d$$ and $$t$$ particles gives grounds to state that these fragments arise via a local mechanism of their direct knockout from nuclei. The results were obtained in the SPIN experiment at the Institute for High Energy Physics (IHEP, Protvino).
