摘要

If the HyperCP three events for the decay of Σ+ → p μ+ μ- are explained by a new pseudoscalar (axial-vector) boson XP (A) with a mass of 214.3 MeV, we study the constraints on the couplings between XP (A) and fermions from the experimental data in K and B processes. Some implications of the new particle on flavor changing B and τ decays are given. Explicitly, we show that the decay branching ratios of Bs → φ{symbol} XP (A) → φ{symbol} μ+ μ-, Bd → K0* (1430) P (A) → K0* (1430) μ+ μ- and τ → μ XP (A) → μ μ+ μ- can be as large as 2.7 (2.8) × 10-6, 7.4 (7.5) × 10-7 and 1.7 (0.14) × 10-7, respectively.
