Abstract

We present first results on the $ρ$ resonance parameters obtained with $N_{f} = 2 + 1 + 1$ Wilson twisted mass fermions at maximal twist. Using ensembles of the ETM collaboration, we provide results for two values of the lattice spacing and a range of pion mass values.

Comments: 7 pages, 3 figures. Poster presented at the 33rd International Symposium on Lattice Field Theory, 14 -18 July 2015 (Kobe, Japan)
