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…

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…

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^…
