Sigma(+) and (Sigma)over-bar(-) Polarization in the J/psi and psi(3686) Decays
(Amer Physical Soc., 2020)
From 1310.6 x 10(6) J/psi and 448.1 x 10(6) psi (3686) events collected with the BESIII experiment, we report the first observation of Sigma(+) and (Sigma) over bar (-) spin polarization in e(+)e(-) -> J/psi[psi(3686)] -> ...
Measurement of J/psi -> Xi(1530+)(-) (Xi)over-bar(+) and evidence for the radiative decay Xi(153)(-) -> gamma Xi(-)
(Amer Physical Soc., 2020)
The SU(3)-flavor violating decay J/psi -> Xi(1530)(-) (Xi) over bar (+) + c.c. is studied using (1310.6 +/- 7.0) x 10(6) J/psi events collected with the BESIII detector at BEPCII, and the branching fraction is measured to ...
Search for the decay J/psi -> gamma plus invisible
(Amer Physical Soc., 2020)
We search for J/psi radiative decays into a weakly interacting neutral particle, namely an invisible particle, using the J/psi produced through the process psi(3686) -> pi(+)pi(-) J/psi in a data sample of (448.1 +/- 2.9) ...
Effect of Soil-Structure Interaction on the Seismic Response of Existing Low and Mid-Rise RC Buildings
(MDPI, 2020)
Reconnaissance studies performed after destructive earthquakes have shown that seismic performance of existing buildings, especially constructed on weak soils, is significantly low. This situation implies the negative ...
Search for intermediate resonances and dark gauge bosons in J/psi -> gamma pi(0)eta '
(Amer Physical Soc., 2020)
We report on an analysis of the decay J/psi -> gamma pi(0)eta' using a sample of o1310.6 +/- 7.0THORN x 10(6) J/psi events collected with the BESIII detector. We search for the CP-violating process eta c -> pi(0)eta' and ...
Study of e(+)e(-) -> D+D-pi(+)pi(-) at center-of-mass energies from 4.36 to 4.60 GeV
(Elsevier, 2020)
We report a study of the e(+)e(-) -> D+D-pi(+)pi(-) process using e(+)e(-) collision data samples with an integrated luminosity of 2.5 fb(-1) at center-of-mass energies from 4.36 to 4.60 GeV, collected with the BESIII ...
Measurement of Cross Section for e(+)e(-) -> Xi(0)(Xi)over-bar(0) Near Threshol
(Elsevier, 2021)
Using e(+)e(-) collision data at ten center-of-mass energies between 2.644 and 3.080 GeV collected with the BESIII detector at BEPCII and corresponding to an integrated luminosity of about 500 pb(-1), we measure the cross ...
Practical Evidence-Based Evaluation of a Combined Heat Reduction Technique for Power Transformer Buildings
(MDPI, 2020)
Transformer buildings are at the heart of the effective operation of distribution systems, and heating problems of transformers under severe operational conditions are among the main factors affecting the lifetime, efficiency, ...
Search for the Charged Lepton Flavor Violating Decay J/psi -> e tau
(Amer Physical Soc., 2021)
A search for the charged lepton flavor violating decay J/psi -> e(+/-)tau(-/+) with tau(-/+) -> pi(-/+)pi(0)nu(tau) is performed with about 10 x 10(9) J/psi events collected with the BESIII detector at the BEPCII. No ...
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 ...
