Constraints on the new particle in $Σ^{+} \to p μ^{+} μ^{-}$

C. Q. Geng, Y. K. Hsiao

The HyperCP collaboration has presented the branching ratio of $Σ^{+} \to p μ^{+} μ^{-}$ to be $(8. 6_{- 5.4}^{+ 6.6} \pm 5.5) \times 1 0^{- 8}$ and suggested a new boson $P^{0}$ with a mass of $214…

T Violation in Baryonic B Decays

C. Q. Geng, Y. K. Hsiao

We study $T$ violation in the three-body charmless baryonic decay of $\bar B^0 \ra Λ\bar p π^+$ through the $T$ -odd triple product correlation in the standard model. We find that t…
