Measurement of Born Cross Section for $e^{+} e^{-} \to K_{S}^{0} I^ˉ ^{+} I^£^{-} + c.c.$ at $s = 3.51 - 4.95$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $e^{+} e^{-}$ collision data collected with the BESIII detector at the BEPCII collider corresponding to a total integrated luminosity of 44~fb $^{- 1}$ , 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…

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 $10.09 \times 1 0^{9}$ $J / I ¨ $ events at BESIII, the…
