Partial wave analysis of J/ψ →γη η

Ablikim, M.; Achasov, M.N.; Adlarson, P.; Ahmed, S.; Albrecht, M.; Aliberti, R.; Amoroso, A.; An, M.R.; An, Q.; Bai, X.H.; Bai, Y.; Bakina, O.; Cetin, S. A.; Kolcu, O.B. (American Physical Society, 2022)

Using a sample of (10.09±0.04)×109 J/ψ events collected with the BESIII detector, a partial wave analysis of J/ψ→γη η is performed. The masses and widths of the observed resonances and their branching fractions are reported. ...
Search for baryon- and lepton-number violating decays D0 → p ¯ e+ and D0 →pe-

Ablikim, M.; Achasov, M.N.; Adlarson, P.; Ahmed, S.; Albrecht, M.; Aliberti, R.; Amoroso, A.; An, M.R.; An, Q.; Bai, X.H.; Bai, Y.; Bakina, O. (American Physical Society, 2022)

Using an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb-1 collected with the BESIII detector at a center-of-mass energy of 3.773 GeV, we search for the baryon-number and ...
Study of light scalar mesons through Ds+ →π0π0e+νe and KS0 KS0 e+νe decays

Ablikim, M.; Achasov, M.N.; Adlarson, P.; Ahmed, S.; Albrecht, M.; Aliberti, R.; Amoroso, A.; An, M.R.; An, Q.; Bai, X.H.; Bai, Y.; Bakina, O.; Kolcu, O.B. (American Physical Society, 2022)

Using 6.32 fb-1 of e+e- collision data recorded by the BESIII detector at center-of-mass energies between 4.178 to 4.226 GeV, we present the first measurement of the decay Ds+→f0(980)e+νe,f0(980)→π0π0. The product branching ...
