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, ...
Measurement of the leptonic decay width of J/psi using initial state radiation
(Elsevier, 2016)
Using a data set of 2.93 fb(-1) taken at a center-of-mass energy of root s = 3.773 GeV with the BESIII detector at the BEPCII collider, we measure the process e(+) e(-) -> J/psi gamma -> mu(+)mu(-)gamma and determine the ...
Evidence for the singly Cabibbo suppressed decay Lambda(+)(c) -> p eta and search for Lambda(+)(c) -> p pi(0)
(Amer Physical Soc., 2017)
We study the singly Cabibbo suppressed decays Lambda(+)(c) -> p eta and Lambda(+)(c) -> p pi(0) using Lambda(+)(c)(Lambda) over bar (-)(c) pairs produced by e(+)e(-) collisions at a center-of-mass energy of root s = 4.6 ...
Observation of the helicity-selection-rule suppressed decay of the chi(c2) charmonium state
(Amer Physical Soc., 2017)
The decays of chi(c2) -> K+K- pi(0), KSK +/-pi(-/+), and pi(+)pi(-)pi(0) are studied with the psi(3686) data samples collected with the Beijing Spectrometer ( BESIII). For the first time, the branching fractions of chi(c2) ...
Observation of a Neutral Structure near the D(D)over-bar* Mass Threshold in e(+)e(-) -> (D(D)over-bar*)(0)pi(0) at root s=4.226 and 4.257 GeV
(Amer Physical Soc., 2015)
A neutral structure in the D (D) over bar* system around the D (D) over bar* mass threshold is observed with a statistical significance greater than 10 sigma in the processes e(+)e(-) -> D+D*(-)pi(0) + c.c. and e(+)e(-) ...
Determination of the Spin and Parity of the Z(c)(3900)
(Amer Physic Soc., 2017)
The spin and parity of the Z(c)(3900)(+/-) state are determined to be J(P) = 1(+) with a statistical significance larger than 7 sigma over other quantum numbers in a partial wave analysis of the process e(+)e(-) -> pi(+)pi(-) ...
Windowed Scalogram Entropy: Wavelet-Based Tool to Analyze the Temporal Change of Entropy of a Time Series
(Springer, 2021)
In this paper, we propose a new entropy calculation method to observe the temporal change of the entropy of dynamical systems. The proposed entropy calculation method is based on the windowed scalogram which has been ...
Toward Class AAA LED Large Scale Solar Simulator with Active Cooling System for PV Module Tests
(IEEE Electron Devices Society, 2022)
Solar simulators are significant in testing solar cells and photovoltaic (PV) modules since they provide spectrum and optic characteristics close to natural sunlight. This research introduces two fundamental novelties to ...
Chronology of trace elements and radionuclides using sediment cores in Golden Horn Estuary, Sea of Marmara
(Elsevier Ltd, 2022)
Trace elements and radionuclides are substantial pollutants in marine environment since they are non-biodegradable and can be harmful even in minute concentrations. The Golden Horn estuary, where is an inlet of Bosphorus ...
