Abstract
We review recent lattice QCD results from the CSSM using the variational method to isolate the L(1405) and explore its structure. The behaviour of the electric and magnetic form factors as the up and down quark masses approach their physical values, together with a Hamiltonian effectivefield-Theory model analysis of the lattice QCD energy levels, reveal that the structure is dominated by a bound antikaon-nucleon component [1].
