In a lattice QCD calculation with two light dynamical chirally improved quarks we determine ground state and some excited state masses in all four Lambda baryon channels 1/2(+/-) and 3/2(+/-). We perform an infinite volume extrapolation and confirm the widely discussed Lambda (1405). We also analyze the amount of octet-singlet mixing, which is helpful in comparing states with the quark model. DOI: 10.1103/PhysRevD.87.034502
