Description
We present a lattice calculation of the mass and width for the rho meson by determining the energy dependent phaseshift for pi-pi scattering in isospin-1, spin-1 channel in the elastic region. We compute the energy spectrum from spatially asymmetric boxes. We use Nf=2 nHYP fermions and generate two sets of ensembles with pion masses of 300MeV and 220MeV. To determine the energy spectrum we perform a variational analysis with interpolating fields including several q-\bar{q} and pi-pi interpolating fields.
