Measurements of the electric and magnetic form factors of the neutron for time-like momentum transfer

BESIII Collaboration, M. Ablikim, M. N. Achasov +589

We present the first measurements of the electric and magnetic form factors of the neutron in the time-like (positive $q^{2}$ ) region as function of four-momentum transfer. We explor…

Search for a massless dark photon in $Λ_{c}^{+} \to p γ^{'}$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +569

A search for a massless dark photon $γ^{'}$ is conducted using 4.5 $fb^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.600 and 4.699 $…

Measurement of the branching fraction and decay asymmetry of $Λ \to nγ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +565

The radiative hyperon decay $Λ \to nγ$ is studied using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector operating at BEPCII. The absolute branching fractio…

Observation of $χ_{c J} \to Λ Λ ˉ η$

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

By analyzing $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decays of $χ_{c J} \to Λ Λ ˉ η$ ( $J = 0$ , 1 and 2) ar…

Observation of resonance structures in $e^{+} e^{-} \to π^{+} π^{-} ψ_{2} (3823)$ and mass measurement of $ψ_{2} (3823)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +547

Using a data sample corresponding to an integrated luminosity of 11.3 $f b^{- 1}$ collected at center-of-mass energies from $4.23$ to $4.70$ GeV with the BESIII detector, we meas…
