Further Evidence for Pignotti'sRTrajectory

The high-energy $K^{\pm }p$ and $K^{\pm }n$ total cross section and the $K^{-}+p\to {\overline{K}}^0+n$ charge-exchange data contain further evidence for the Regge trajectory $R$ proposed by Pignotti. The signature factor is important in fitting these data; thus there is also some support for the Regge-pole hypothesis itself.
