A new particle Σ^ * with J ^P = 1/2^-was predicted by unquenched quark models with its mass around the well established Σ * (1385) with J P = 3/2 + .Here we re-examine some old data of the K^-p → Λπ^-π^ + ...

Complementary to the conventional experimental studies on N* from πN and γ(*)N reactions, the e+e-, pp and pp collisions can give novel insights into these N* resonances. While the e+e- collisions through pro...
