Corrections of the B meson baryogengesis model to lifetimes of B mesons. — •Ali Mohamed, Alexander Lenz, Maria Laura Piscopo, Aleksey Rusov, and Zachary Wüthrich — Siegen university
The framework of B meson Baryogenesis by Alonso-Álvarez, Elor, and Escudero aims at describing the matter-antimatter asymmetry and the existence of dark matter in the Universe by introducing new decay channels of the b quark. These new decay channels could also modify other observables, e.g. the lifetime ratio of B+ and Bd mesons. We perform a study of the possible size of these new contributions to τ(B+) / τ (Bd) within the framework of the Heavy Quark Expansion.
