[[abstract]]If the HyperCP three events for the decay of Sigma(+) -> p mu(+)mu(-) are explained by a new pseudoscalar (axial-vector) boson X-P(A) with a mass of 214.3 MeV, we study the constraints on the couplings between X-P(A) and fermions from the experimental data in K and B processes. Some implications of the new particle on flavor changing B and tau decays are given. Explicitly, we show that the decay branching ratios of B-s -> phi X-P(A) -> phi mu +mu(-), B-d -> K-0*(1430)P(A) -> K-0*(1430)mu(+)mu(-) and tau -> mu X-P(A) -> mu mu(+)mu(-) can be as large as 2.7 (2.8) X 10(-6), 7.4 (7.5) x 10(-7) and 1.7 (0.14) x 10(-7), respectively.[[fileno]]2010129010093[[department]]物理
