Understand

In this project, we will compute the form factors relevant for $B \to K^*(\to K \pi)\ell^+\ell^-$ decays.

To map the finite-volume matrix elements computed on the lattice to the infinite-volume $B \to K \pi$ matrix elements, the $K \pi$ scattering amplitude needs to be determined using L\"uscher's method.
Here we present preliminary results from our calculations with $2+1$ flavors of dynamical clover fermions.
We extract the $P$-wave scattering phase shifts and determine the $K^*$ resonance mass and the $K^* K \pi$ coupling for two different ensembles with pion masses of $317(2)$ and $178(2)$ MeV.
