${{\boldsymbol K}{(3100)}}$ $I^G(J^{PC})$ = $?^?(?^{? ?})$ 

Narrow peak observed in several ( ${{\mathit \Lambda}}{{\overline{\mathit p}}}$ + pions) and ( ${{\overline{\mathit \Lambda}}}{{\mathit p}}$ + pions) states in ${{\mathit \Sigma}^{-}}{}^{}\mathrm {Be}$ reactions by BOURQUIN 1986 and in ${{\mathit n}}{{\mathit p}}$ and ${{\mathit n}}$ A reactions by ALEEV 1993 . Not seen by BOEHNLEIN 1991 . If due to strong decays, this state has exotic quantum numbers ($\mathit B=0,\mathit Q=+1,\mathit S=-1$ for ${{\mathit \Lambda}}{{\overline{\mathit p}}}{{\mathit \pi}^{+}}{{\mathit \pi}^{+}}$ and $\mathit I$ ${}\geq{}$ 3$/$2 for ${{\mathit \Lambda}}{{\overline{\mathit p}}}{{\mathit \pi}^{-}}$ ). Needs confirmation.
