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…

Search for sub-GeV dark particles in $η \to π^{0} + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using (10087 $\pm$ 44) $\times$ 10 $^{6}$ $J / ψ$ events collected with the BESIII detector at the BEPCII collider at the center-of-mass energy of $s = 3.097 GeV$ , we report the…
