Heavy flavor pentaquarks with four heavy quarks

Abstract

In this work, we carry out the study of heavy flavor pentatuarks with four heavy quarks, which have typical $QQQQ\bar{q}$ configuration. Within the Chromomagnetic Interaction model, the mass spectrum of these discussed $QQQQ\bar{q}$ 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 effort, we suggest that future experiment should pay attention to this kind of pentaquark.
