Hadron–Hadron interactions from Nf=2+1+1 lattice QCD: the ρ-resonance

We present a lattice QCD investigation of the ρ-meson with Nf=2+1+1 dynamical quark flavours for the first time. The calculation is performed based on gauge configuration ensembles produced by the ETM Collaboration with three lattice spacing values and pion masses ranging from 230 to 500 MeV. Applyi...
