Observation of $ψ (3770) \to η J / ψ$

BESIII Collaboration

The Born cross section of the process $e^{+} e^{-} \to η J / ψ$ at a center-of-mass energy $s = 3.773 GeV$ is measured to be ( $8.89 \pm 0.88 \pm 0.42$ ) $pb$ , using a data…

Determination of U-spin breaking parameters with an amplitude analysis of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +605

We present a study of the resonant structure of the decay $D^{0} \to K_{L}^{0} π^{+} π^{-}$ , using quantum-correlated $D^{0} D ˉ^{0}$ data produced at $s = 3.773$ GeV. The data sampl…

Search for the weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +567

The Cabibbo-allowed weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ has been searched for in a sample of $Λ_{c}^{+} Λ ˉ_{c}^{-}$ pairs produced in $e^{+} e^{-}$ annihilations, corresponding to an i…

First Direct Measurement of the Absolute Branching Fraction of $Σ^{+} \to Λ e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +591

The first direct measurement of the absolute branching fraction of $Σ^{+} \to Λ e^{+} ν_{e}$ is reported based on an $e^{+} e^{-}$ annihilation sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ eve…

Search for a heavy neutrino in $τ$ decays at Belle

Belle Collaboration, D. Liventsev, I. Adachi +189

We report on a search for a heavy neutrino in the decays $τ^{-} \to π^{-} ν_{h}$ , $ν_{h} \to π^{\pm} ℓ - +$ , $ℓ = e, μ$ . The results are obtained using the full data sample collected wit…
