# Chiral extrapolation of the rho(770) meson in Nf=2+1 simulations

## Content

Recently, phase shift data for the $\rho$-meson have been extracted from several $N_f = 2 + 1$ lattice simulations for diff erent pion masses. We analyze the lattice data sets with Unitarized Chiral Pertubation Theory. Chiral extrapolations are performed to postdict experimental phase shift data, and also compared with the ones obtained from the analysis of $N_f = 2$ lattice data. The low-energy constants from di fferent analyses are compared for consistency. Finally, the role of the $K\bar{K}$ channel is revisited.
