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 events at BESIII, the…
Search for sub-GeV dark particles in decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using (1008744)10 events collected with the BESIII detector at the BEPCII collider at the center-of-mass energy of , we report th…
Helicity amplitude and branching fraction measurement of
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
Utilizing million events accumulated by the BESIII experiment, we perform a partial wave analysis of $Ï(3686)\rightarrowγÏ_{cJ}\rightarrowγÎ\barÎ…
First Measurement of the Absolute Branching Fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +691
We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay with the BESIII experiment at BEPCII. Starting with a large initia…
