Towards next-to-next-to-leading-log accuracy for the width difference in the system: fermionic contributions to order and
H. M. Asatrian, Artyom Hovhannisyan, Ulrich Nierste +1
We calculate a class of three-loop Feynman diagrams which contribute to the next-to-next-to-leading logarithmic approximation for the width difference in the $B_s-\bar{B}_…
Neutral decays as discovery channels for charm CP violation
Ulrich Nierste, Stefan Schacht
We point out that the CP asymmetries in the decays and are potential discovery channels for charm CP violat…
: Standard Model and Supersymmetry
Ulrich Nierste
I give a pedagogical introduction into flavour-changing neutral current interactions of kaons and their role to reveal or constrain physics beyond the Standard Model (SM). Then I d…
Penguin pollution in and
Ulrich Nierste
The mixing-induced CP asymmetries in and are essential to detect or constrain new physics in the and $B_s\! - \overline…
CP asymmetries in decays
Ulrich Nierste, Stefan Schacht
This talk addresses two topics related to CP asymmetries in meson decays to two pseudoscalar mesons. First I discuss how new physics can be distinguished from the Standard Mode…
in the MSSM in Light of the Anomaly
Andreas Crivellin, Giancarlo D'Ambrosio, Teppei Kitahara +1
The Standard-Model (SM) prediction for the CP-violating quantity deviates from its measured value by 2.8 . It has been shown that this tension can be resolved…
