Domain Wall Charm Physics with Physical Pion Masses: Decay constants, bag and $ξ$ parameters

We provide an overview of RBC/UKQCD's charm project on 2+1 flavour physical pion mass ensembles using Möbius Domain Wall Fermions for the light as well as for the charm quark. We discuss the analysis strategy in detail and present results at the different stages of the analysis for $D$ and $D_s$ decay constants as well as the bag and $ξ$ parameters. We also discuss future approaches to extend the reach in the heavy quark mass.
