Title: B-Mesogenesis: Baryogenesis and Dark Matter from B Mesons
Abstract: In this seminar, based on 1810.00880 and 2101.02706, I will present a
new mechanism of Baryogenesis and Dark Matter production: B-Mesogenesis.
Within the B-Mesogenesis paradigm, 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^{-4}.
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 a BR > 10^{-4}.
I will discuss the reach of current collider experiments to these
signatures, and I will show that a combination of measurements at BaBar,
Belle, Belle II, LHCb, ATLAS & CMS can fully test B-Mesogenesis.
