Abstract

A comprehensive study of the electromagnetic strangeness production has been undertaken at Thomas Jefferson National Accelerator Facility (Jefferson Lab). Here will be reported the analysis of the measurement on the γ n ( p ) → K + Σ − ( p ) made with the CLAS detector in Hall-B. The main motivation for this work is to provide data to investigate the spectrum of non strange (N* and Δ) baryon resonances decaying in KY ( Y ≡ Λ or Σ ) final states and to improve the predictive power of the present theoretical description of hyperon photoproduction by adding more constraints to the Kaon-Hyperon-Nucleon coupling constants.
