Observation of the Semileptonic D+ Decay into the K 1 (1270)0 Axial-Vector Meson
(American Physical Society, 2019)
By analyzing a 2.93 fb-1 data sample of e+e- collisions, recorded at a center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we report the first observation of the semileptonic D+ ...
Observation of the Leptonic Decay D+ →τ+ντ
(American Physical Society, 2019)
We report the first observation of D+→τ+ντ with a significance of 5.1σ. We measure B(D+→τ+ντ)=(1.20±0.24stat±0.12syst)×10-3. Taking the world average B(D+→μ+νμ)=(3.74±0.17)×10-4, we obtain Rτ/μ=Γ(D+→τ+ντ)/Γ(D+→μ+νμ)=3.21 ...
First observation of the decay χcJ → ς+ p KS0 + c. c. (J=0,1,2) FIRST OBSERVATION of the DECAY ... ABLIKIM M. et al
(American Physical Society, 2019)
Using E1 radiative transitions ψ(3686)→γχcJ from a sample of (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector, the decays χcJ→ς+pKS0+c.c.(J=0,1,2) are studied. The decay branching fractions are measured ...
Measurement of branching fractions for D meson decaying into ϕ meson and a pseudoscalar meson
(Elsevier B.V., 2019)
The four decay modes D0→ϕπ0, D0→ϕη, D+→ϕπ+, and D+→ϕK+ are studied by using a data sample taken at the centre-of-mass energy s=3.773 GeV with the BESIII detector, corresponding to an integrated luminosity of 2.93 fb−1. The ...
Observation of psi(3886) -> Xi(1530)(-)(Xi)over-bar(1530)(+) and Xi(1530)(-)(Xi)over-bar(+)
(AMER PHYSICAL SOC, 2019)
Using 448.1 x 10(6) psi(3686) events collected with the BESIII detector at BEPCII, we employ a single-baryon tagging technique to make the first observation of psi(3686) -> Xi(1530)(-)(Xi) over bar (1530)(+) and Xi(1530)(-)(Xi) ...
The Moderating Roles of Remote, Hybrid, and Onsite Working on the Relationship between Work Engagement and Organizational Identification during the COVID-19 Pandemic
(MDPI, 2022)
Flexible working practices have become commonplace due to the emergence of the turbulent environment that emerged during the COVID-19 pandemic, which forced organizations to change their business models, structures, ...
Search for the decay eta ' -> gamma gamma eta
(AMER PHYSICAL SOC, 2019)
Using a data sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, a search for eta' -> gamma gamma eta via J/psi ->gamma eta' is performed for the first time. No significant eta' signal is observed in ...
Search for a massless dark photon in Λc+ →pγ′ decay
(American Physical Society, 2022)
A search for a massless dark photon γ′ is conducted using 4.5 fb-1 of e+e- collision data collected at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at BEPCII. No significant signal is observed, ...
Cross section measurements of e(+)e(-) -> K+ K- K+ K- and phi K+ K- at center-of-mass energies from 2.10 to 3.08 GeV
(AMER PHYSICAL SOC, 2019)
We measure the Born cross sections of the process e(+)e(-) -> K+ K- K+ K- at center-of-mass (c.m.) energies, root s, between 2.100 and 3.080 GeV. The data were collected using the BESIII detector at the BEPCII collider. ...
Observation of a structure in e(+)e(-) -> phi eta ' at root s from 2.05 to 3.08 GeV
(Amer Physical Soc., 2020)
The process e(+)e(-) -> phi eta' has been studied for the first time in detail using data sample collected with the BESIII detector at the BEPCII collider at center of mass energies from 2.05 to 3.08 GeV. A resonance with ...
