Description
We present an update on the RBC/UKQCD collaboration’s calculation of the kaon semileptonic form factor at zero momentum transfer, $f_{+}^{K \pi}(0)$. This calculation utilizes two new $N_{f} = 2+1$ M\"{o}bius Domain Wall Fermion ensembles which allow us to simulate QCD directly at physical pion mass for the first time. Together with our previous results we now have a complete set of measurements extending from the $SU(3)$ symmetric limit down to the physical point, allowing us to minimize systematic error associated with the chiral extrapolation.
