Abstract We provide details to several technical aspects which are important for the calculation of next-to-next-to-leading order corrections to the mixing of neutral B mesons. This includes the computation of the master integrals for finite charm an

Abstract We complete the calculation of the element Γ 12 q $$ {\Gamma}_{12}^q $$ of the decay matrix in B q − B ¯ q $$ {B}_q-{\overline{B}}_q $$ mixing, q = d, s, to order α s in the leading power of the Heavy Quark Expansion. To this end we com

Abstract Dark matter models with light mediators featuring sizable interactions among dark particles enjoy an increasing attention in the model building community due to the elegance with which they can potentially explain the scaling relations gover

Abstract Yukawa-type interactions between heavy Dirac fermions and a scalar field are a common ingredient in various extensions of the Standard Model. Despite of that, the non-relativistic limit of the scalar Yukawa theory has not yet been studied in

Abstract We consider two-loop QCD corrections to the element Γ 12 q $$ {\Gamma}_{12}^q $$ of the decay matrix in B q − B ¯ q $$ {\overline{B}}_q $$ mixing, q = d, s, in the leading power of the Heavy Quark Expansion. The calculated contributions

In this work we address the issue of large perturbative uncertainties in the theory prediction for $\Delta \Gamma_s$, the width difference in the $B^0_s - \bar{B}^0_s$ mixing process. To this aim we complete important steps towards the full analyt

Abstract The energy-energy correlation (EEC) function in e + e − annihilation is currently the only QCD event shape observable for which we know the full analytic result at the next-to-leading order (NLO). In this work we calculate the EEC observab
