Amplitude analysis and branching fraction measurement of D-s(+) -> K-K+pi(+)pi(+)pi(-)

Ablikim M.; Achasov M.N.; Adlarson P.; Ahmed S.; Albrecht M.; Kolcu, O. B. (Springer Science and Business Media Deutschland GmbH, 2022)

Using e+e− annihilation data corresponding to a total integrated luminosity of 6.32 fb−1 collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of ...

Amplitude analysis and branching-fraction measurement of Ds+ → π + π 0 η′

Ablikim M.; Achasov M.N.; Adlarson P.; Ahmed S.; Albrecht M.; Aliberti R.; Kolcu, O. B. (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 J/Psi Electromagnetic Dalitz Decays to X(1835), X(2120), and X(2370)

Ablikim, M.; Achasov M.N.; Adlarson P.; Ahmed S.; Albrecht M.; Kolcu, O. B. (American Physical Society, 2022)

Using a sample of about 1010 J/ψ events collected at a center-of-mass energy s=3.097 GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e+e-π+π-η′, with η′→γπ+π- and η′→π+π-η, have been studied. The decay ...

Observation of the double Dalitz decay eta' -> e(+)e(-)e(+)e(-)

Ablikim M.; Achasov M.N.; Adlarson P.; Albrecht M.; Aliberti R.; Kolcu, O. B. (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 ...
