Role of the strange quark in the ρ(770) meson
Recently, the GWU lattice group has evaluated high-precision phase-shift data for ππ scattering in the I = 1, J = 1 channel. Unitary Chiral Perturbation Theory describes these data well around the resonance region and for different pion masses. Moreover, it allows to extrapolate to the physical poin...
