Chiral partners of strange doubly heavy baryons: Mass relations and decay predictions after the 2026 LHCb discoveries

Three spectacular LHCb measurements in 2026---the observations of $Ω_{cc}^{+}$, $Ξ_{cc}^{+}$, and the beauty-strange structure $B_{s0}^{*}(5700)^0$---make possible an experimentally constrained analysis of chiral partners of strange doubly heavy baryons. The doubly charmed masses test the earlier Ma
