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

Abstract

We study the masses and lifetimes of doubly charmed pentaquark $P_{cc\bar{q}qq}(q=u,d,s)$ primarily. The operation of masses carried out by the doubly heavy triquark-diquark model, whose results suggests the existence of stable states $cc\bar{s}ud$ with the parity $J^P={\frac{1}{2}}^{-}$. The roughly calculation about lifetimes show the short magnitudes, $(4.65_{-0.55}^{+0.71})\times 10^{-13}s$ for the parity $J^P={\frac{1}{2}}^{-}$ and $(0.93_{-0.11}^{+0.14})\times 10^{-12}s$ for $J^P={\frac{3}{2}}^{-}$. Since the pentaquark $cc\bar{s}ud$ 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.
