Differentiable Multi-scale Effective Field Theory Likelihoods for Beyond the Standard Model Phenomenology

Aleks SmolkoviÄ, Peter Stangl

Probing heavy new physics beyond the Standard Model (SM) increasingly relies on global effective field theory (EFT) likelihoods. We introduce differentiable, multi-scale EFT likeli…

Large Hadronic Effects in $B \to K^{*} I^¼ I^¼$ ?

Wolfgang Altmannshofer, Samuel G. Christensen, Peter Stangl

Recent results from LHCb have confirmed the long-standing $P_{5}^{'}$ anomaly, an intriguing discrepancy in the angular distribution of the $B \to K^{*} I^¼^{+} I^¼^{-}$ decay that might b…

Flavour Physics Beyond the Standard Model

Wolfgang Altmannshofer, Peter Stangl

Flavour physics plays a central role in the search for physics beyond the Standard Model, posing fundamental questions whose answers may point to new physics scales far above the e…

On the Interplay of Constraints from $B_{s}$ , $D$ , and $K$ Meson Mixing in $Z^{'}$ Models with Implications for $b \to s I^½ I^ˉ ½$ Transitions

Andrzej J. Buras, Peter Stangl

Within $Z^{'}$ models, neutral meson mixing severely constrains beyond the Standard Model (SM) effects in flavour changing neutral current (FCNC) processes. However, in certain…
