Measurement of Born Cross Section for at GeV
BESIII Collaboration, M. Ablikim, M. N. Achasov +759
Using collision data collected with the BESIII detector at the BEPCII collider corresponding to a total integrated luminosity of 44~fb, we present the first measure…
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…
Amplitude analysis and branching fraction measurement of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
An amplitude analysis of the decay is performed to determine the relative magnitudes and phases of different intermediate processes. The analysis uses $e^…
First Observation of and Determination of the Branching Fraction of
BESIII Collaboration, M. Ablikim, M. N. Achasov +685
Using 20.3~fb of annihilation data collected at a center-of-mass energy of 3.773~GeV with the BESIII detector, we report the first observation of the semileptonic d…
Observation of Polarization and Determination of Its Electric and Magnetic Moments in
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
The BESIII experiment observed the polarization of the hyperon Ξ(1530)^0 in ψ(3686)→Ξ(1530)^0 anti‑Ξ(1530)^0 decays and measured its electric and magnetic multipole moments via ang…
Precise measurements of and decays
BESIII Collaboration, M. Ablikim, M. N. Achasov +758
Using collision data corresponding to an integrated luminosity of 20.3 fb, collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we present…
