Description
We present preliminary results for the $\rho(770)$ and $K^*(892)$ resonances using the Lüscher method. This work employs distillation on an RBC-UKQCD $N_f=2+1$ domain-wall fermion lattice with a physical pion mass. We consider irreducible representations with only leading $P-$wave contributions and extract the associated low-lying energy levels. These are used to parametrise the scattering phase shifts. We study systematic errors resulting from the choice of fit ranges through a model-averaging technique.
