Design of nonuniform substrate dielectric lens antennas using 3D printing technology
(John Wiley and Sons Inc., 2020)
With the latest developments in 3D printing technologies and decreases in their costs, these prototyping methods are now being used extensively in many applications for fast, low-cost, and precise prototyping. In this work, ...
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) ...
A novel design of high performance multilayered cylindrical dielectric lens antenna using 3D printing technology
(IJMEF, 2020)
In this work, design and realization of high performance, low-cost X-band multilayered cylindrical dielectric lens antenna (MLCDLA) is presented using 3D printing technology. Firstly, MLCDLA is designed and simulated in ...
Observation of e(+)e(-) -> eta ' J/psi center-of-mass energies between 4.189 and 4.600 GeV

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 ...
Amplitude analysis and branching-fraction measurement of Ds+ → π + π 0 η′
(Springer Science and Business Media Deutschland GmbH, 2022)
Using data collected with the BESIII detector in e+e− collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb−1 of integrated luminosity, we report the amplitude analysis and ...
