Determining for the first time the Darwin operator contribution for the non-leptonic charm-quark decays and using new non-perturbative results for the matrix elements of ∆C = 0 four-quark operators, including eye-contractions, we present a comprehens...

SU(3) breaking effects in B and D meson lifetimes (2022)
Journal Article
King, D., Lenz, A., & Rauh, T. (2022). SU(3) breaking effects in B and D meson lifetimes. Journal of High Energy Physics, 2022(6), Article 134. https://doi.org/10.1007/jhep06%282022%29134

In the heavy quark expansion (HQE) of the total decay rates of Bs and D+s mesons non-perturbative matrix elements of four quark operators are arising as phase space enhanced contributions. We present the first determination of ms effects to the dimen... Read More about SU(3) breaking effects in B and D meson lifetimes.

Bs mixing observables and |Vtd/Vts| from sum rules (2019)
Journal Article

We consider the effects of a non-vanishing strange-quark mass in the determination of the full basis of dimension six matrix elements for Bs mixing, in particular we get for the ratio of the V − A Bag parameter in the Bs and Bd system: B s Q1 /B d Q1...
