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 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 resonance, we perform the first measurement of the relative phase between the strong and electromagnetic ampli…
Updated measurement of the branching fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
Using a dataset of 7.33 fb of annihilation data collected with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report an updated measure…
Measurement of transverse polarization of and hyperons inside jets in collisions at GeV
STAR Collaboration, B. E. Aboona, J. Adam +363
A surprisingly large transverse polarization of hyperons in unpolarized hadron-nucleon/nucleus collisions has been observed for 50 years, and the origin of this polarization r…
