Search for the charged lepton flavour violating decay $η^{'} \to e μ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

Based on $(8998 \pm 40) \times 1 0^{6}$ $J / ψ$ events collected in $e^{+} e^{-}$ collisions at $s = 3.097$ GeV with the BESIII detector, we present a search for the charged lepton flavou…

Study of the $e^{+} e^{-} \to π^{+} π^{-} D_{s}^{+} D_{s}^{-}$ process from $s$ = 4.42 to 4.95 GeV at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +782

Based on $8.5 fb^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.42 and 4.95 GeV with the BESIII detector at the BEPCII storage ring, we inves…

First Measurement of the $D_{s}^{+} \to K^{0} μ^{+} ν_{μ}$ Decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +693

We report the first measurement of the semileptonic decay $D_{s}^{+} \to K^{0} μ^{+} ν_{μ}$ , using a sample of $e^{+} e^{-}$ annihilation data corresponding to an integrated luminosity of $…

Search for a hypothetical gauge boson and dark photons in charmonium transitions

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

We report a direct search for a new gauge boson, $X$ , with a mass of $17 MeV / c^{2}$ , which could explain the anomalous excess of $e^{+} e^{-}$ pairs observed in the $^{8} Be$ n…

Study of the Magnetic Dipole Transition of $J / ψ \to γ η_{c}$ via $η_{c} \to p p ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +692

Using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the $e^{+} e^{-}$ BEPCII collider, we present the first amplitude analysis of $J / ψ \to γ p p ˉ$ wit…
