Heavy flavor pentaquarks with four heavy quarks

Abstract

In this work, we carry out the study of heavy flavor pentaquarks with four heavy quarks, which have typical $QQQQ\overline{q}$ configuration. Within the chromomagnetic interaction model, the mass spectrum of these discussed $QQQQ\overline{q}$ pentaquarks is given. In addition to the mass spectrum analysis, we also illustrate their two-body strong decay behavior by estimating some ratios of decay channels. By these efforts, we suggest that a future experiment should pay attention to this kind of pentaquark.
