Amplitude analysis and branching fraction measurement of Ds+ →k-K+π+π0
(American Physical Society, 2021)
The first amplitude analysis of the decay Ds+→K-K+π+π0 is presented using the data samples, corresponding to an integrated luminosity of 6.32 fb-1, collected with the BESIII detector at e+e- center-of-mass energies between ...
Amplitude analysis and branching-fraction measurement of Ds+ → π + π 0 η′
(Springer Science and Business Media Deutschland GmbH, 2022)
Using data collected with the BESIII detector in e+e− collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb−1 of integrated luminosity, we report the amplitude analysis and ...
Observation of the double Dalitz decay eta' -> e(+)e(-)e(+)e(-)
(Observation of the double Dalitz decay η′ →e+e-e+e-, 2022)
Based on (10087±44)×106 J/ψ events collected with the BESIII detector at BEPCII, the double Dalitz decay η′→e+e-e+e-is observed for the first time via the J/ψ→γη′ decay process. The significance is found to be 5.7σ with ...
Study of the resonance structures in the process e+e- →π+π-J/ψ
(American Physical Society, 2022)
Using about 23 fb-1 of data collected with the BESIII detector operating at the BEPCII storage ring, a precise measurement of the e+e-→π+π-J/ψ Born cross section is performed at center-of-mass energies from 3.7730 to 4.7008 ...
