NLO analysis of the subleading-power $Q_{1} - Q_{7 γ}$ interference in $B ˉ \to X_{s} γ$ at large photon energies

Riccardo Bartocci, Philipp Böer, Tobias Hurth

We report on progress towards including next-to-leading order (NLO) radiative corrections to the subleading-power factorization formula for the $Q_{1}^{q} - Q_{7 γ}$ interference contri…

Renormalisation group evolution effects on global SMEFT analyses

Riccardo Bartocci, Anke Biekötter, Tobias Hurth

Global analyses in the Standard Model Effective Field Theory (SMEFT) framework serve as a tool to probe potential directions of new physics. To break degeneracies between the Wilso…

Renormalisation group evolution of the shape function $g_{17}$ in $B ˉ \to X_{s} γ$ and $B ˉ \to X_{s} ℓ^{+} ℓ^{-}$ at subleading power

Riccardo Bartocci, Philipp Böer, Tobias Hurth

We derive and solve the renormalisation-group (RG) equation of the shape function $g_{17} (ω, ω_{1}; μ)$ , which appears at subleading power in the factorization of the inclusive decays…
