  The similar densities of dark matter and baryons in the universe imply that
they might arise from the same ultraviolet model. The B-Mesogenesis, which
assumes dark matter is charged under the baryon number, attempts to
simultaneously explain the origin of baryon asymmetry and dark matter in the
universe. In particular, the B-Mesogenesis might induce bottom-baryon decays
into invisible or semi-invisible final states, which provide a distinctive
signal for probing this scenario. In this work, we systematically study the
invisible decays of bottom baryons into dark matters, and semi-invisible decays
of bottom baryons into a meson or a photon together with a dark matter
particle. In particular, the fully invisible decay can explore the stable
particles in B-Mesogenesis. Some QCD-based frameworks are used to calculate the
hadronic matrix elements under the B-Mesogenesis model. We estimate the
constraints on the Wilson coefficients or the product of some new physics
couplings with the Wilson coefficients by the semi-invisible and invisible
decays of bottom baryons at future colliders.
