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…

Precise Measurement of Chromoelectric Dipole Moment of the Charm Quark

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

The combined symmetry of charge conjugation and parity ( $C P$ ) is tested in the hadronic transition $ψ (3686) \to π^{+} π^{-} J / ψ$ , using a dataset of $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ(3686…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ cross section in the vicinity of 3.872 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

We report a measurement of the cross section for the process $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ around the $X (3872)$ mass in search for the direct formation of $e^{+} e^{-} \to X (3872)$ through the tw…
