Search for sub-GeV invisible particles in inclusive decays of $J / ψ$ to $ϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +696

A search for an invisible particle, $X$ , with a mass between 0 and 0.96 $GeV / c^{2}$ , is performed in the process $J / ψ \to ϕ + X$ using $(8774.0\pm39.4)\times…

Updated model-independent measurement of the strong-phase differences between $D^{0}$ and $D ˉ^{0} \to K_{S / L}^{0} π^{+} π^{-}$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +688

The strong-phase differences between $D^{0} \to K_{S / L}^{0} π^{+} π^{-}$ and $D ˉ^{0} \to K_{S / L}^{0} π^{+} π^{-}$ decays are one of the most important inputs in measuring the $C P$ violating angle…

Search for $e^{+} e^{-} \to K_{S}^{0} K_{S}^{0} h_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using $e^{+} e^{-}$ collision data at 13 center-of-mass energies ranging from 4.600 to 4.950 GeV collected with the BESIII detector, we search for the unmeasured $e^+e^-\to K_S^0 K_S^0…

Determination of spin and parity of $D_{(s)}^{*}$ mesons

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

The spin and parity of the charmed mesons $D_{s}^{*+}$ , $D^{* 0}$ and $D^{*+}$ are determined for the first time to be $J^{P} = 1^{-}$ with significances greater than 10 $σ$ over other h…
