Abstract
We present a preliminary analysis of I = 1 $\pi$ $\pi$ scattering at the physical point. We make use of
the stochastic variant of the distillation framework (also known as sLapH) to compute the relevant
two-point correlation matrices using a basis of single and multihadron interpolating operators to
estimate the low energy spectra. We perform the Lüscher analysis to determine the scattering
phase shift which is finding good agreement with the experimentally obtained phase shifts.
