Abstract

We search for dimuon decays of a low mass particle in the decays B0→K^*0X and B0→ρ0X using a data sample of 657×106BB̄ events collected with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider. We find no evidence for such a particle in the mass range from 212MeV/c2 to 300MeV/c2 for lifetimes below 10^-12s, and set upper limits on its branching fractions. In particular, we search for a particle with a mass of 214.3MeV/c2 reported by the HyperCP experiment, and obtain upper limits on the products B(B0→K ^*0X)×B(X→μ⁺μ^-)<2. 26(2.27)×10^-8 and B(B0→ρ0X) ×B(X→μ⁺μ^-)<1.73(1.73)×10 ^-8 at 90% C.L. for a scalar (vector) X particle.
