Investigations on the low-lying triply charmed pentaquark states in a constituent quark model

In present work, mass spectrum of the low-lying cccqq pentaquarks states with qq=uu, dd and ss, are investigated employing a constituent quark model, within which the spin-dependent hyperfine interactions are taken to be the instanton-induced interaction and the one-gluon-exchange interaction, respectively. The model parameters are fixed by fitting the mass spectrum of the relative qq and qqq traditional hadrons. The numerical results show that energies for all the obtained states in the two employed models are higher than corresponding meson-baryon channels, consequently, we roughly estimate strong decays of these states using a simple quark rearrangement model, the corresponding partial width ratios for different decay channels are presented.
