Search for the familon via B-+/-->pi X-+/-(0), B-+/-->(KX0)-X-+/-, and B-0 ->(KSX0)-X-0 decays

A search for the decay of the meson B±→H±X0 and B0→Ks0X0 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 involvi...
