The study of doubly charmed pentaquark cc(q)over-barqq with the SU(3) symmetry

We study the masses and lifetimes of doubly charmed pentaquark P-cc (q) over bar qq(q = u, d, s) primarily. The operation ofmasses carried out by the doubly heavy triquarkdiquarkmodel, whose results suggests the existence of stable states cc (s) over bar ud with the parity J(P) = 1/2(-). The roughly calculation about lifetimes showthe shortmagnitudes, (4.65(-0.55)(+0.71))x 10(-13)s for the parity J(P) = 1/2(-) and (0.93(-0.11)(+0.14)) x10(-12)s for J(P) = 3/2(-). Since the pentaquark cc (s) over bar ud is interpreted as the stable bound states against strong decays, then we will focus on the production and possible decay channels of the pentaquark in the next step, the study would be fairly valuable supports for future experiments. For completeness, we systematically studied the production from Omega(ccc) and the decay modes in the framework SU(3) flavor symmetry, including the processes of semi-leptonic and two body non-leptonic decays. Synthetically, we make a collection of the golden channels.

Automated summary

This study focuses on the masses and lifetimes of doubly charmed pentaquark P-cc (q) over bar qq(q = u, d, s). Stable states with short lifetimes were found, and the focus will now shift to the production and possible decay channels of the pentaquark. The research on production from Omega(ccc) and decay modes within the framework of SU(3) flavor symmetry is expected to provide valuable support for future experiments.
