Amplitude analysis and branching fraction measurement of the decay D-s(+) -> pi(+)pi(0)pi(0)
(SPRINGER, 2022)
Using a data set corresponding to an integrated luminosity of 6.32fb(-1) recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, an amplitude analysis of the decay D-s(+) -> pi(+)pi(0)pi(0 ...
Measurements of the absolute branching fractions of hadronic D -meson decays involving kaons and pions
(American Physical Society, 2022)
By analyzing an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb-1 taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we obtain for the first time the ...
Observation of the doubly Cabibbo-suppressed decays D+ -> K+ pi(0)pi(0) and D+ -> K+ pi(0)eta
(SPRINGER, 2022)
By analyzing e(+)e(-) annihilation data corresponding to an integrated luminosity of 2.93 fb(-1) collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first observations of the doubly ...
Observation of the double Dalitz decay η′ →e+e-e+e-
(American Physical Society, 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 ...
Measurement of the e(+) e(-) -> omega pi(0)pi(0) cross section at center-of-mass energies from 2.0 to 3.08 GeV
(AMER PHYSICAL, 2022)
The cross section of the process e(+)e(-) -> omega pi(0)pi(0) is measured at nineteen center-of-mass energies from 2.0 to 3.08 GeV using data collected with the BESIII detector at the BEPCII storage ring. A resonant structure ...
Measurement of psi(3686) -> lambda(lambda)over-bar eta and psi(3686) -> lambda(lambda)over-bar pi(0) decays
(AMER PHYSICAL SOC, 2022)
Based on a sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector, a study of psi(3686) -> Lambda(Lambda) over bar pi(0) and psi(3686) -> Lambda(Lambda) over bar eta is performed. Evidence of the ...
Observation of chi(cJ) -> lambda(lambda)over-bar(eta)
(PHYSICAL REVIEW D, 2022)
By analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of chi(cJ) -> Lambda(Lambda) over bar (eta) (J = 0, 1, and 2) are observed for the first ...
