Electromagnetic form factors for the Λ(1405)

Abstract

Building on our successful technique to isolate the otherwise-elusive Λ(1405) using correlation matrix techniques and multiple source and sink smearings, we present calculations of the quark sector contributions to the electric form factors of the Λ(1405). Using the PACS-CS (2+1)- flavour full-QCD ensembles available through the ILDG, our calculations reveal behaviour consistent with the development of a non- Trivial molecular KN bound-state component as one approaches the physical values of the u and d quark masses.
