Search for the lepton number violation decay $ω \to π^{+} π^{+} e^{-} e^{-} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

The lepton number violation decay $ω \to π^{+} π^{+} e^{-} e^{-} + c . c .$ is searched for via $J / ψ \to ω η$ using a data sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected by…

Search for the FCNC charmonium decay $J / ψ \to D^{0} μ^{+} μ^{-} + c.c.$

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

Based on a data sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events taken with the BESIII detector, we search for the flavor-changing neutral current charmonium decay $J/ψ\to D^{0}…

Improved measurement of absolute branching fraction of the inclusive decay $Λ_{c}^{+} \to K_{S}^{0} X$

BESIII Collaboration, M. Ablikim, M. N. Achasov +676

By analyzing $4.5$ fb $^{- 1}$ of $e^{+} e^{-}$ collision data accumulated with the BESIII detector at center-of-mass energies ranging from $4599.53$ MeV to $4698.82$ MeV, we report t…
