Abstract
We present a lattice QCD investigation of the ρ resonance using nine N(f) = 2 + 1 Wilson-Clover ensembles with three lattice spacings and various pion masses ranging from 135 to 320 MeV. For each ensemble, a large number of finite volume energy levels are determined and the energy dependence of the phase shift obtained from Lüscher’s finite volume method. The mass and width of the ρ resonance are then extracted by assuming the Breit-Wigner form...
