Abstract

We present our exploratory study with the aim of simulating heavy-light semileptonic form factors as part of the RBC-UKQCD charm (to bottom) physics programme. We are using a distillation-based setup as a strategy to get optimised plateaus in semileptonic D₍s₎ and B₍s₎ decays, and compare our results to form factors obtained from sequential Z₂-Wall propagators. The study is done in a centre-of-mass frame as well as in several moving frames. We use an N_f = 2+1 domain wall fermion ensemble with a pion mass of 340 MeV, with the aim of extending the study to a variety of other domain-wall ensembles, including physical-pion mass ensembles.
