Lambda Baryon Spectroscopy and Pion-Pion Scattering with Partial Wave Mixing in Lattice QCD

The spectrum of [lambda] three-quark excitations and [pion pion] scattering, with partial-wave mixing,are studied using lattice QCD. These low-lying stationary-state energies in QCD
are calculated as correlation lengths in a statistical field theory. Monte Carlo methods with importance sampling estimate the multidimensional path integral, with 412 gauge configurations generated according to a clover-improved Wilson action with 2 + 1 flavors of quarks.
