### Description

We report a direct lattice calculation of both the I=0 and 2 pi-pi scattering phase shifts using G-parity boundary conditions on an ensemble of $32^3\times64$ gauge configurations at physical quark mass. This extends an earlier calculation of the RBC/UKQCD Collaboration by including additional operators and using non-zero center-of-mass momenta. We apply the generalized eigenvalue treatment to this set of operators in order to understand and reduce excited state contamination and to study pi-pi scattering at energies in the energy region around the kaon mass. These results are compared with results from Roy's equation.
