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…
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…
Evidence for a quasi-bound state in the reaction
R. Kobayakawa, J. K. Ahn, S. Ajimura +34
The authors measured the γd → K⁰Λp reaction with the LEPS2 spectrometer and observed a localized enhancement below the K⁻pp threshold, which they interpret as evidence for a K̄NN q…
Search for an isoscalar partner of the in
BESIII Collaboration, M. Ablikim, M. N. Achasov +684
Using a data sample corresponding to an integrated luminosity of 20.3 fb collected at center-of-mass energies from 4.18 to 4.95 GeV with the BESIII detector, we observe the…
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…
