Description
In this talk, based on arXiv:1810.00880 and ongoing work, I will present a new mechanism of Baryogenesis and Dark Matter production in which both the dark matter relic abundance and the baryon asymmetry arise from neutral B meson oscillations and subsequent decays in the early Universe.
This mechanism would have distinctive experimental signals that I will discuss in detail:
i) the new decay mode of B mesons into a baryon and missing energy, with a BR > 10^{-3}.
ii) a positive semileptonic asymmetry in neutral B meson decays, > 10^{-5}.
iii) the new decay mode of b-flavored baryons into mesons and missing energy, with BR > 10^{-3}.
These unique collider signatures are testable at current collider experiments, such as the LHC and Belle-II, allowing for a distinct probe of this mechanism.
