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…
