Observation of D0(+) -> K-S(0)pi(0(+))omega and improved measurement of D-0 -> K- pi(+)omega
(AMER PHYSICAL SOC, 2022)
By analyzing an e(+)e(-) annihilation data sample with an integrated luminosity of 2.93 fb(-1) taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions of the ...
Measurement of the doubly Cabibbo-suppressed decay D+ -> K+pi(+)pi(-)pi(0) with semileptonic tags
(American Physical Society, 2021)
We propose a new semileptonic tag method to study the doubly Cabibbo-suppressed D decay in ψ(3770)→DD¯ reaction. Utilizing the dataset corresponding to an integrated luminosity of 2.93 fb-1 at a center-of-mass energy of ...
Measurement of the branching fraction of leptonic decay D-s(+) -> tau(+)nu(tau) via tau(+) -> pi(+)pi(0)(tau)
(American Physical Society, 2021)
By analyzing 6.32 fb-1 of e+e- annihilation data collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we determine the branching fraction of the leptonic decay Ds+→τ+ντ, with ...
Measurements of weak decay asymmetries of Lambda(+)(c) -> pK(S)(0), Lambda pi(+), Sigma(+)pi(0), and Sigma(0)pi(+)

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 ...
