Flavour physics in the $D_{(s)}$ and $B_{(s)}$ meson system

Abstract:
After a brief motivation, I will present our (domain wall fermion) charm and bottom physics program. I will first focus on our very recent computation (arXiv:1812.08791) of SU(3) breaking ratios in the $D_{(s)}$ and $B_{(s)}$ meson systems and the ratios of CKM matrix elements $V_{cd}/V_{cs}$ and $V_{td}/V_{ts}$. I will then outline the current status of our wider heavy flavour phenomenology program in the charm and bottom sector.
