Search for lepton number violating decays of $D_{s}^{+} \to h^{-} h^{0} e^{+} e^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

Based on 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector operating at the BEPCII collider at center-of-mass energies from 4.128 to 4.226 GeV, a search fo…

First observation of the M1 transition $ψ (3686) \to γ η_{c} (2 S)$

M. Ablikim, M. N. Achasov, D. J. Ambrose +356

Using a sample of 106 million ψ(3686) events collected with the BESIII detector at the BEPCII storage ring, we have made the first measurement of the M1 transition between the radi…
