${{\mathit K}{(3100)}}$

$I^G(J^{PC})$ = $?^?(?^{? ?})$ 

also known as ${{\mathit K}_{{{J}}}^{?}{(3100)}}$
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.
