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…
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…
Amplitude analysis and branching fraction measurement of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
An amplitude analysis of the decay is performed to determine the relative magnitudes and phases of different intermediate processes. The analysis uses $e^…
Search for an isoscalar partner of the in
BESIII Collaboration, M. Ablikim, M. N. Achasov +684
Using a data sample corresponding to an integrated luminosity of 20.3 fb collected at center-of-mass energies from 4.18 to 4.95 GeV with the BESIII detector, we observe the…
Observation and branching fraction measurements of and
BESIII Collaboration, M. Ablikim, M. N. Achasov +765
Using events and events collected by the BESIII detector operating at the BEPCII collider, we report the…
