Description
We present updated results on the scattering of pseudoscalar, vector,
and scalar mesons on a physical pion mass, 2+1 flavor mobius-DWF,
ensemble with periodic boundary conditions (PBCs) generated by the RBC
and UKQCD collaborations. Using all-to-all propagators, we produce
thousands of correlator momentum combinations. Energy spectra and phase
shifts, including excited states, are then extracted via the solutions
of a generalized eigenvalue problem. Included in this talk will also
be an overview of improved analysis techniques and a second lattice spacing.
These studies are intended to serve as groundwork for a full PBC
calculation of direct CP violation in K->pipi later this year.
