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…

Measurement of Born cross sections for at GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

We report a measurement of the Born cross section and the effective form factor for the reaction at 47 center-of-mass energies between 3.510 and 4.946 GeV. The…

Observation of and Measurement of Electromagnetic Form Factors of Proton at GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

We search for possible charmonium(-like) states decaying into the final state by studying the Born cross sections of the reaction, and we determine…

Measurements of the absolute branching fractions of the hadronic decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +722

Based on 4.5 fb of collision data collected at center-of-mass energies between 4599.53 MeV and 4698.82 MeV with the BESIII detector, the absolute branching fraction…
