1. QCD improved matching for semileptonic B decays with leptoquarks / Aebischer, Jason ; Crivellin, Andreas ; Greub, Christoph
Leptoquarks (LQs) provide very promising solutions to the tensions between the experimental measurements and the SM predictions of bs+ and bcτν processes. [...]

2. Importance of Loop Effects in Explaining the Accumulated Evidence for New Physics in B Decays with a Vector Leptoquark / Crivellin, Andreas ; Greub, Christoph ; Saturnino, Francesco ; Müller, Dario
In recent years experiments revealed intriguing hints for new physics (NP) in B decays involving bcτν and bs+ transitions at the 4σ and 5σ level, respectively. [...]

3. The MSSM without gluinos; an effective field theory for the stop sector / Aebischer, Jason ; Crivellin, Andreas ; Greub, Christoph ; Yamada, Youichi
In this article we study the MSSM with stops and Higgs scalars much lighter than gluinos and squarks of the first two generations. [...]

4. B physics beyond the Standard Model at one loop: complete renormalization group evolution below the electroweak scale / Aebischer, Jason ; Fael, Matteo ; Greub, Christoph ; Virto, Javier
General analyses of B -physics processes beyond the Standard Model require accounting for operator mixing in the renormalization-group evolution from the matching scale down to the typical scale of B physics. [...]

5. Matching of gauge invariant dimension-six operators for b → s and b → c transitions / Aebischer, Jason ; Crivellin, Andreas ; Fael, Matteo ; Greub, Christoph
New physics realized above the electroweak scale can be encoded in a model independent way in the Wilson coefficients of higher dimensional operators which are in-variant under the Standard Model gauge group. [...]
