Observation of the doubly radiative decay eta ' -> gamma gamma pi(0)
(Amer Physical Soc., 2017)
Based on a sample of 1.31 billion J/psi events collected with the BESIII detector, we report the study of the doubly radiative decay eta' -> gamma gamma pi(0) for the first time, where the eta' meson is produced via the ...
Branching fraction measurements of psi (3686) -> gamma chi(cJ)
(Amer Physical Soc., 2017)
Using a sample of 106 million psi(3686) decays, the branching fractions of psi(3686) -> gamma chi(c0), psi(3686) -> gamma chi(c1), and psi(3686) -> gamma chi(c2) are measured with improved precision to be (9.389 +/- 0.014 ...
Investigation of Microhardness Properties of the Multi-Walled Carbon Nanotube Additive Mgb2 Structure By Using The Vickers Method
(Elsevier, 2021)
In this study, the effect of multi-walled carbon nanotube doping to MgB2 compound on microhardness properties of MgB2 was investigated by using solid-state reaction method. The amount of multi-walled carbon nanotubes was ...
Search for the radiative leptonic decay D+ -> gamma e (+) nu(e)
(Amer Physical Soc., 2017)
Using an electron-positron collision data sample of 2.93 fb(-1) collected at a center-of-mass energy of root s = 3.773 GeV with the BESIII detector, we present the first search for the radiative leptonic decay D+ -> gamma ...
Measurement of higher-order multipole amplitudes in psi(3686) -> gamma chi(c1,2) with chi(c1,2) -> gamma J/psi and search for the transition eta(c)(2S) -> gamma J/psi
(Amer Physical Soc., 2017)
Using 106 x 10(6) psi(3686) events collected with the BESIII detector, we measure multipole amplitudes for the decay psi(3686) ->; gamma chi(c1,2) -> gamma gamma J/psi beyond the dominant electric-dipole amplitudes. The ...
Development of Educational Optical Mark Recognition System With NI Labview
