Measurement of integrated luminosity and center-of-mass energy of data taken by BESIII at root s=2.125 GeV
(Chinese Physical, 2017)
To study the nature of the state Y (2175), a dedicated data set of e(+)e(-) collision data was collected at the center-of-mass energy of 2.125 GeV with the BESIII detector at the BEPCII collider. By analyzing large-angle ...
Spectrum Measurement of Variable Irradiance Controlled LED-Based Solar Simulator
(Int Journal Renewable Energy Research, 2020)
Efficiency of photovoltaic devices are based on testing all equipment and systems used to produce devices in a healthy way, from electrical and optical points of view. Considering that photovoltaic devices which enable the ...
Study of decay dynamics and CP asymmetry in D+ ? KL0 e+?e decay
(American Physical Society, 2015)
Using 2.92 fb-1 of electron-positron annihilation data collected at s=3.773 GeV with the BESIII detector, we obtain the first measurements of the absolute branching fraction B(D+?KL0e+?e)=(4.481±0.027(stat)±0.103(sys))% ...
Evidence of Two Resonant Structures in e(+)e(-)->pi(+) pi(-) h(c)
(Amer Physic Soc., 2017)
The cross sections of e(+)e(-) -> pi(+) pi(-) hc at center-of-mass energies from 3.896 to 4.600 GeVare measured using data samples collected with the BESIII detector operating at the Beijing Electron Positron Collider. The ...

We report the first direct measurement of decays of the Lambda(+)(c) baryon involving the neutron. The analysis is performed using 567 pb(-1) of e(+)e(-) collision data collected at root s = 4.599 GeV with the BESIII ...
Investigation of The Effect of Temperature on The Structural and Magnetic Properties of MgB2 Superconductor Produced Using Boron Doped with Carbon by CVD Method
(Gazi Üniversitesi, 2021)
Carbon, which is known to play a improvement role on the superconductivity properties of MgB2, was doped into MgB2 by CVD (chemical vapor deposition) method, and the change of structural and magnetic properties observed ...
Search for psi(3686)-> gamma eta(c)(eta(1405)) -> gamma pi(+)pi(-)pi(0)
(Amer Physical Soc., 2017)
Using a sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector, a search for the isospin violating decay eta(c) -> pi(+) pi(-) pi(0) via psi(3686) -> gamma eta(c) is presented. No signal is observed, ...
