Electromagnetic form factors of the Lambda(1405) in (2+1)-flavour lattice QCD

Extent: 7p.The Λ(1405) is unusual in that it lies surprisingly low in mass. At 1405.1 MeV, it lies lower than the lowest-lying odd-parity state of the nucleon, even though it contains a valence strange quark. We build on our recent success in isolating this otherwise elusive state in lattice QCD using correlation matrix techniques coupled with source and sink smearing, and present first results from our world-first calculation of the electromagnetic form factors of this unusual state. We use the PACS-CS (2+1)-flavour full-QCD ensembles, available through the ILDG.Benjamin J. Menadue, Waseem Kamleh, Derek B. Leinweber, M. Selim Mahbub, Benjamin J.
