Evidence for and observation of
BESIII Collaboration, M. Ablikim, M. N. Achasov +771
Using events collected by the BESIII detector at the BEPCII collider, the process is investigated. Evidence…
Search for the charged lepton flavour violating decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +765
Based on events collected in collisions at GeV with the BESIII detector, we present a search for the charged lepton flavou…
Measurement of Born Cross Section for at GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +759
Using collision data collected with the BESIII detector at the BEPCII collider corresponding to a total integrated luminosity of 44~fb, we present the first measure…
First Measurement of the Relative Phase between Proton Psionic Form Factors
BESIII Collaboration, M. Ablikim, M. N. Achasov +754
The relative phase between the time-like form factors of the proton is a crucial observable for a complete understanding of its internal structure, yet it has remained unmeasured d…
Proof of principle for nucleon polarization measurement at BESIII
BESIII Collaboration, M. Ablikim, M. N. Achasov +754
A novel technique for measuring the spin polarization of final-state nucleons in a general-purpose spectrometer is validated. Using events at BESIII, the…
Observation of via
BESIII Collaboration, M. Ablikim, M. N. Achasov +766
The study reports the first observation of the decay η_c → p p̄ η using a large ψ(3686) data set collected with the BESIII detector, and determines its branching fraction while acc…
