The study of doubly charmed pentaquark $$c c {\bar{q}}qq$$ c c q ¯ q q with the SU(3) symmetry

Abstract We study the masses and lifetimes of doubly charmed pentaquark $$P_{cc{\bar{q}}qq}(q=u,d,s)$$ P c c q ¯ q q ( q = u , d , s ) primarily. The operation of masses carried out by the doubly heavy triquark-diquark model, whose results suggests the existence of stable states $$cc{\bar{s}} ud$$ c...
