Author(s): Xu Cao, Jian-Ping Dai, and Ya-Ping Xie The measured electromagnetic form factors of Λ hyperon in the timelike region are significantly deviated from pQCD prediction. We attribute the nonvanishing cross section near threshold to be the contribution of below-threshold ϕ ( 2170 ) state, supporting its exotic structure. Above the threshold, we ... [Phys. Rev.
