Abstract

A search for the decay of the meson B±→H±X0 and B0→Ks 0X0 was performed. The upper limits for the branching fractions constrained new physics leading to two-body B decays involving any massless neutral feebly interacting particle X0. The first lower bound on the family symmetry breaking scale involving the third generation of quarks at 108 GeV was obtained by applying the limit to the case where X0 was a familon.
