Search for a massless particle beyond the Standard Model in the $Σ^{+} \to p + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

A massless particle beyond the Standard Model is searched for in the two-body decay $Σ^{+} \to p + invisible$ using $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected…

Search for the semi-leptonic decays $Λ_{c}^{+} \to Λ π^{+} π^{-} e^{+} ν_{e}$ and $Λ_{c}^{+} \to p K_{S}^{0} π^{-} e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +595

We search for the semi-leptonic decays $Λ_{c}^{+} \to Λ π^{+} π^{-} e^{+} ν_{e}$ and $Λ_{c}^{+} \to p K_{S}^{0} π^{-} e^{+} ν_{e}$ in a sample of 4.5 $fb^{- 1}$ of $e^{+} e^{-}$ annihilation data coll…

Direct Measurements of Absolute Branching Fractions for D0 and D+ Inclusive Semimuonic Decays

BES Collaboration, M. Ablikim

By analyzing about 33 $p b^{- 1}$ data sample collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we directly measure the branching fractions for the…

Production of $σ$ in $ψ (2 S) \to π^{+} π^{-} J / ψ$

BES Collaboration, M. Ablikim

Using 14M $ψ (2 S)$ events accumulated by BESII at the BEPC, a Covariant Helicity Amplitude Analysis is performed for $ψ (2 S) \to π^{+} π^{-} J / ψ, J / ψ \to μ^{+} μ^{-}$ . The $π^{+} π^{-}$ mass spectrum,…
