Measurement of e(+)e(-)-> K+K-pi(0) cross section and observation of a resonant structure
(SPRINGER, 2022)
Based on e(+)e(-) collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e(+)e(-)-> K+K-pi(0). The ...
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 ...
Observation of psi (3686) ->Xi (1530)(0) (Xi)over-bar (1530)(0) and Xi (1530)(0) (Xi)over-bar(0)
(AMER PHYSICAL SOC, 2021)
Using (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the BESIII detector and a single-baryon tagging technique, we present the first observation of the decays psi(3686)-> Xi (1530)(0) (Xi) over bar (1530)(0) and ...
Measurement of integrated luminosities at BESIII for data samples at center-of-mass energies between 4.0 and 4.6 GeV*
(IOP Publishing Ltd, 2022)
The integrated luminosities of data samples collected in the BESIII experiment in 2016-2017 at center-of-mass energies between 4.19 and 4.28 GeV are measured with a precision better than 1% by analyzing large-angle Bhabha ...
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 ...
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 ...
Search for invisible decays of the Λ baryon
(American Physical Society, 2022)
A search for invisible decays of the Λ baryon is carried out in the process J/ψ→ΛΛ¯ based on (1.0087±0.0044)×1010 J/ψ events collected with the BESIII detector located at the BEPCII storage ring. No signals are found for ...
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 ...
