Measurements of weak decay asymmetries of Lambda(+)(c) -> pK(S)(0), Lambda pi(+), Sigma(+)pi(0), and Sigma(0)pi(+)
(AMER PHYSICAL SOC, 2019)
Using e(+)e(-) -> Lambda(+)(c)(Lambda) over bar (-)(c). production from a 567 pb(-1) data sample collected by BESIII at 4.6 GeV, a full angular analysis is carried out simultaneously on the four decay modes of Lambda(+)(c) ...
Observation of e(+)e(-) -> eta ' J/psi center-of-mass energies between 4.189 and 4.600 GeV
(AMER PHYSICAL SOC, 2016)
The process e(+)e(-) -> eta' J/psi is observed for the first time with a statistical significance of 8.6 sigma at center-of-mass energy root s = 4.226 GeV and 7.3 sigma at root s = 4.258 GeV using data samples collected ...
Searches for isospin-violating transitions χc0,2 → π0ηc
(American Physical Society, 2015)
We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions χc0,2 → π0ηc. The measurements are performed using 106×106ψ(3686) events accumulated with the BESIII detector at ...
Improved measurements of χcJ → Σ+ Σ - and Σ0 Σ 0 decays IMPROVED MEASUREMENTS of ... M. ABLIKIM et al.
(American Physical Society, 2018)
Using a data sample of (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector at the BEPCII collider, we present measurements of branching fractions for the decays χcJ→Σ+Σ- and Σ0Σ0. The decays χc1,2→Σ+Σ- and ...
Observation of a Neutral Charmoniumlike State Zc (4025)0 in e+e- → (D∗ D ¯ ∗)0π0
(American Physical Society, 2015)
We report a study of the process e+e-→(D∗D¯∗)0π0 using e+e- collision data samples with integrated luminosities of 1092 pb-1 at s=4.23 GeV and 826 pb-1 at s=4.26 GeV collected with the BESIII detector at the BEPCII storage ...
