Abstract

A new mechanism has been proposed to simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the Universe. This scenario predicts exotic B -meson decays into a baryon and a dark-sector antibaryon (ψ D ) with branching fractions accessible at B factories. We present a search for B→ΛψD decays using data collected by the BABAR experiment at SLAC. This reaction is identified by fully reconstructing the accompanying B meson and requiring the presence of a single Λ baryon in the remaining particles. No significant signal is observed, and bounds on the B → Λ ψ D branching fraction are derived in the range 0.13 – 5.2 × 10 − 5 for 1.0 < m ψ D < 4.2 GeV / c 2. These results set strong constraints on the parameter space allowed by the theory.
