$B$ -meson decay width up to $1/ m_{b}^{3}$ corrections within and beyond the Standard Model

Martin Lang, Alexander Lenz, Ali Mohamed +2

Starting from the most general effective $∣ I^ B ∣ = 1$ Hamiltonian describing non-leptonic $b$ -quark decays $b \to q_{1} q ˉ_{2} q_{3}$ , we compute analytic expressions for all matching…

HQET sum rules for matrix elements of dimension-six four-quark operators for meson lifetimes within and beyond the Standard Model

Matthew Black, Martin Lang, Alexander Lenz +1

Theory predictions of heavy-hadron lifetime ratios critically depend on precise determinations of the dimension-six spectator effects arising from the double insertion of the weak…
