The identification of flavored multiskyrmions with the ground states of known hypernuclei is successful for several of them, e.g. for isodoublet H(Lambda) - He(Lambda), A=4, isoscalars He(Lambda) (A=5) and Li(Lambda) (A=7). In other cases…

The low mass of the $\Lambda(1405)$ hyperon with $j^P = 1/2^-$, which is higher than the ground state $\Lambda(1116)$ mass by 290 MeV, is difficult to understand in quark models. We analyze the hyperon spectrum in the bound state approach…

We study the possibility that four iso-singlet baryons $\Lambda_s(1405)$ $J^P=1/2^{-}$, $\Lambda_s(1520)$ $J^P=3/2^{-}$, $\Lambda_c(2593)$ $J^P=1/2^{-}$ and $\Lambda_c(2625)$ $J^P=3/2^{-}$ are hybrids: three quark one gluon states (udsg).…
