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…
Cross Section Measurements of via Antineutrons Produced by Decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +759
Based on a novel method for producing antineutrons via decays, we report a study of inelastic scattering into final states containing kaons. The analysis uses $(1…
Observation of and
BESIII Collaboration, M. Ablikim, M. N. Achasov +750
Using events collected with the BESIII detector at a center-of-mass energy of GeV, the antihyperon-nucleon annihilation process…
