Abstract
We establish upper limits on branching fractions for B⁰ decays to final states where the decay products are purely invisible (i.e., no observable final state particles) and for B⁰ decays to νν̅ γ. Within the standard model, these decays have branching fractions that are below current experimental sensitivity, but various models of physics beyond the standard model predict significant contributions from these channels. Using 88.5×10⁶ BB̅ pairs collected at the Υ(4S) resonance by the BABAR experiment at the PEP-II e⁺e⁻ storage ring at the Stanford Linear Accelerator Center, we establish upper limits at the 90% confidence level of 22×10⁻⁵ for the branching fraction of B⁰→invisible and 4.7×10⁻⁵ for the branching fraction of B⁰→νν̅ γ.
