Query: A Supersymmetric Theory of Baryogenesis and Sterile Sneutrino Dark
  Matter from $B$ Mesons   Low-scale baryogenesis and dark matter generation can occur via the
production of neutral $B$ mesons at MeV temperatures in the early Universe,
which undergo CP-violating oscillations and subsequently decay into a dark
sector. In this work, we discuss the consequences of realizing this mechanism
in a supersymmetric model with an unbroken $U(1)_R$ symmetry which is
identified with baryon number. $B$ mesons decay into a dark sector through a
baryon number conserving operator mediated by TeV scale squarks and a GeV scale
Dirac bino. The dark sector particles can be identified with sterile neutrinos
and their superpartners in a type-I seesaw framework for neutrino masses. The
sterile sneutrinos are sufficiently long lived and constitute the dark matter.
The produced matter-antimatter asymmetry is directly related to observables
measurable at $B$ factories and hadron colliders, the most relevant of which
are the semileptonic-leptonic asymmetries in neutral $B$ meson systems and the
inclusive branching fraction of $B$ mesons into hadrons and missing energy. We
discuss model independent constraints on these experimental observables before
quoting predictions made in the supersymmetric context. Constraints from
astrophysics, neutrino physics and flavor observables are studied, as are
potential LHC signals with a focus on novel long lived particle searches which
are directly linked to properties of the dark sector.
