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

Tobias Tsang (U. of Edinburgh)

After a brief motivation, I will present two studies of our (domain wall fermion) charm and bottom physics program. In the first part I will focus on our 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 $V_td/V_ts$.

In the second part I will describe our ongoing efforts to compute semi-leptonic $B_(s)$ decays (arXiv:1903.02100) before concluding by summarising RBC/UKQCD’s wider efforts in charm and bottom phenomenology.
