Predictions for $b$ -baryon lifetimes at NNLO-QCD

Alexander Lenz, Maria Laura Piscopo, Aleksey V. Rusov

Motivated by recent and forthcoming experimental progress, we provide updated predictions for the total decay rates of $b$ -baryons, their lifetime ratios and their lifetimes normal…

One-loop matching of QCD currents to power-suppressed two-jet operators

Martin Beneke, Aleksey V. Rusov, Michel Stillger

We compute the matching of QCD quark-antiquark currents onto the set of the two-particle and three-particle two-jet operators in soft-collinear effective theory (SCET) at next-to-l…

$B$ -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…

Total decay rates of $B$ mesons at NNLO-QCD

Manuel Egner, Matteo Fael, Alexander Lenz +4

We update the Standard Model (SM) predictions for the lifetimes of the $B^{+}$ , $B_{d}$ and $B_{s}$ mesons within the heavy quark expansion (HQE), including the recently determined NNLO-…
