Description
I report on our study of low-lying resonances in $\pi\pi$ and $K\pi$ scattering from lattice QCD.
Based on ab-initio multi-hadron spectroscopy and the Lüscher finite-volume method, we have
investigated the elastic scattering amplitudes for $\pi\pi$ P-wave, $K\pi$ S-wave
and P-wave partial waves. A particular focus of the discussion will be the parametrizaton of the amplitudes
with respect to the identification of resonance parameters. The shown results are
obtained for two gauge field ensembles at pion masses $317$ MeV and $178$ MeV.
