Penguin contribution to width difference and CP asymmetry in $B_{q}$ - $B ˉ_{q}$ mixing at order $α_{s}^{2} N_{f}$

Hrachia M. Asatrian, Hrachya H. Asatryan, Artyom Hovhannisyan +3

We present new contributions to the decay matrix element $Γ_{12}^{q}$ of the $B_{q}$ - $B ˉ_{q}$ mixing complex, where $q = d$ or $s$ . Our new results constitute the order $α_{s}^{2} N_{f}$ cor…
