K+N scattering data and exotic Z+ resonances

Abstract

Given the growing evidence for an exotic S = +1 resonance, seen in kaon, photon and neutrino induced reactions, we reexamine the existing K+p and K+d database in order to understand how such a state could have been missed in previous studies. The lack of structure in this database implies a width of an MeV or less, assuming a state exists near 1540 MeV.
