  We introduce and study the first class of signals that can probe the dark
matter in Mesogenesis which will be observable at current and upcoming large
volume neutrino experiments. The well-motivated Mesogenesis scenario for
generating the observed matter-anti-matter asymmetry necessarily has dark
matter charged under baryon number. Interactions of these particles with nuclei
can induce nucleon decay with kinematics differing from sponanteous nucleon
decay. We calculate the rate for this process and develop a simulation of the
signal that includes important distortions due to nuclear effects. We estimate
the sensitivity of DUNE, Super-Kamiokande, and Hyper-Kamiokande to this
striking signal.
