Update of the nonlocal sub-leading $O_{1}$ - $O_{7}$ contribution to $B ˉ \to X_{s} I^^{3}$ at LO

Michael Benzke, Maria Vittoria Garzelli, Tobias Hurth

In all previous calculations of the non-local sub-leading contribution to the inclusive penguin decay $B ˉ \to X_{s} I^^{3}$ due to the interference of the electroweak operators ${O}_…

NLO analysis of the subleading-power $Q_{1} - Q_{7 I^^{3}}$ interference in $B ˉ \to X_{s} I^^{3}$ at large photon energies

Riccardo Bartocci, Philipp BÃ¶er, Tobias Hurth

We report on progress towards including next-to-leading order (NLO) radiative corrections to the subleading-power factorization formula for the $Q_{1}^{q} - Q_{7 I^^{3}}$ interference contr…

Renormalisation group evolution of the shape function $g_{17}$ in $B ˉ \to X_{s} I^^{3}$ and $B ˉ \to X_{s} ℓ^{+} ℓ^{-}$ at subleading power

Riccardo Bartocci, Philipp BÃ¶er, Tobias Hurth

We derive and solve the renormalisation-group (RG) equation of the shape function $g_{17} (I ¨ , I ¨ _{1}; I^¼)$ , which appears at subleading power in the factorization of the inclusive deca…

Renormalisation group evolution effects on global SMEFT analyses

Riccardo Bartocci, Anke BiekÃ¶tter, 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…
