Testing chiral unitary models for the $\Lambda (1405)$ in $K^{+}\pi \Sigma$ photoproduction

P. C. Bruns, A. Cieplý, M. Mai

We adopt a novel formalism for the low-energy analysis of the $\gamma p\to K^{+}\pi \Sigma$ photoproduction reaction to calculate the $\pi \Sigma$ invariant mass distributions in the $\Lambda (1405)$ resonanc…
