Search for baryon- and lepton-number violating decays D0 → p ¯ e+ and D0 →pe-
(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
(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 ...
Partial wave analysis of J/ψ →γη η
(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. ...
