$B$ -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 $∣Δ B ∣ = 1$ Hamiltonian describing non-leptonic $b$ -quark decays $b \to q_{1} q ˉ_{2} q_{3}$ , we compute analytic expressions for all matching c…

David Friday, Evelina Gersabeck, Alexander Lenz +1

50 years after the discovery of the first charmed particle, charm physics continues to be an extremely lively field of research and a cornerstone in particle physics. The study of…
