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…

Unexpected large relative strong phase and search for isospin breaking and $C P$ asymmetries in $J/Ï\to K^*(892)\bar K

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

Using a direct scan of 26 energy points near the $J / I ¨ $ resonance, we perform the first measurement of the relative phase $I ¨ _{I^^{3}, 3 g}$ between the strong and electromagnetic ampli…

Updated measurement of the branching fraction of $D_{s}^{+} \to I ¨ ^{+} I^½_{I ¨} $

BESIII Collaboration, M. Ablikim, M. N. Achasov +703

Using a dataset of 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ annihilation data collected with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report an updated measure…
