Superconducting Materials and Applications

We discuss a simple rotation in the flip non-flip plane, which is undetermined in conventional Regge fits (i.e., those without FESR), and which thus affects the conclusions about mechanism choosing at α = 0. Our t independent effective pole analysis of K±p elastic scattering naturally continues down to pLab = 1.45 GeV/c, where a rotation invariant comparison with the K+p phase shifts is made.
