K+ -nucleon scattering and exotic S=+1 baryons
Abstract
The K+ -nucleon elastic scattering process has been reexamined in light of recent measurements which have found a narrow exotic S=+1 resonance in their KN invariant mass distributions. We have analyzed the existing database in order to consider the effect of a narrow state on fits to K+ -nucleon observables.
