Study of $Λ ˉ$ - $p$ Annihilation into Light Mesons

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

The annihilation of $Λ ˉ$ - $p$ into light mesons is studied using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the BEPCII storage ring. The $\…

First Measurement of the Absolute Branching Fraction of $η_{c} \to γ γ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +691

We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay $η_{c} \to γ γ$ with the BESIII experiment at BEPCII. Starting with a large initial s…

Measurements of the absolute branching fractions of the $Λ_{c}^{+}$ hadronic decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +722

Based on 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4599.53 MeV and 4698.82 MeV with the BESIII detector, the absolute branching fraction…
