Properties of Q5q dibaryons
Abstract
We investigate heavy flavor dibaryons with five heavy quarks Q (Q=\c,b\) and one light quark q (q=\u,d,s\), namely the Q5q dibaryons. In the framework of an extended chromomagnetic model, we systematically study the mass spectrum of these dibaryons. We find no stable state below the corresponding baryon-baryon thresholds. In addition to the analysis of the masses, we also study their two body decay properties by estimating the relative width ratios of the decay channels. We hope our study will be of help for future experiments.
