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 point and estimate the effect of the missing $K\\bar{K}$ channel in the two-flavor lattice calculation. The absence of the strange quark in the lattice data leads to a lower $\\rho$ mass, and the analysis with U$\\chi$PT shows that the $K \\bar{K}$ channel indeed pushes the $\\pi\\pi$-scattering pha","authors_text":"A.
