Search for and branching fraction measurements of via radiative decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +648
Using events collected by the BESIII detector operating at BEPCII, we search for the decay via the process $ψ(2S)\to γη…

Measurement of the branching fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +654
By analyzing collision data with an integrated luminosity of 7.9~fb collected with the BESIII detector at the center-of-mass energy of 3.773~GeV, the branching…

Measurement of the Decay with Entangled Pairs
BESIII Collaboration, M. Ablikim, M. N. Achasov +643
In this Letter, a systematic study of the weak radiative hyperon decay at an electron-positron collider using entangled pair events is presented. The…
