Mass and decay properties of double heavy baryons with a phenomenological potential model

Abstract

Abstract We consider baryons in a nonrelativistic quark model, find the wave function and masses of the baryons with two heavy quarks including $$\Xi _{bc}(bcu)$$ Ξbc(bcu) , $$\Xi _{cc}(ccu)$$ Ξcc(ccu) , $$\Xi _{bb}(bbu)$$ Ξbb(bbu) , $$\Omega _{bb}(bbs)$$ Ωbb(bbs) , $$\Omega _{bc}(bcs)$$ Ωbc(bcs) and $${\Omega _{cc}}(ccs)$$ Ωcc(ccs) . We calculate magnetic moments of these baryons. Using transition magnetic moments, we obtain the radiative decay widths for double heavy baryons. Then we calculate some of the semileptonic decay widths of these baryons. Our results are compared with other theoretical predictions.
