| Abstract | a b → d transition plus an internal quark annihilation that further suppresses the amplitude with respect to rare semileptonic decays. In addition, helicity suppression factors proportional to mν make the νν channel completely undetectable in the SM scenario. For the ννγ channel the latter factor is not present, resulting in SM branching fraction expectations at the 10 level [1]. Several new physics models predict enhancements of these branching ratios up to values close to the experimental detection: a phenomenological model allows for associated neutralino production from B decays with a branching fraction in the 10 to 10 range [2]. Also, models with large extra dimensions can have the effect of producing significant, although small, rates for invisible B decays [3, 4, 5]. The data used in this analysis were collected with the BABAR detector at the PEP-II ee collider at SLAC. The data sample corresponds to a luminosity of |
