Evidence of a Resonant Structure in the e(+) e(-) -> pi(+) (DD)-D-0*(-) Cross Section between 4.05 and 4.60 GeV
(Amer Physic Soc., 2019)
The cross section of the process e(+) e(-) -> pi(+) (DD)-D-0*(-) for center-of-mass energies from 4.05 to 4.60 GeV is measured precisely using data samples collected with the BESIII detector operating at the BEPCII storage ...
Natural gas reserve/production ratio in Russia, Iran, Qatar and Turkmenistan: A political and economic perspective
(Elsevier, 2016)
In this study, changes in natural gas reserve/production ratio (R/P) of the four countries having the highest natural gas reserves (Russia, Iran, Qatar, Turkmenistan), the importance of which increases in the world market ...
Observation of e(+)e(-) -> omega chi(c1,2) near root s=4.42 and 4.6 GeV
(2016)
BEPC-BES. Based on data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies s?>s> 4.4 GeV, the processes e+e-›??c1,2e+e-›??c1,2 are observed for the first time. With ...
Search for C-parity violation in J/? › ?? and ??

Using 1.06×108 ?(3686) events recorded in e+e- collisions at s?=3.686??GeV with the BESIII at the BEPCII collider, we present searches for C-parity violation in J/?›?? and ?? decays via ?(3686)›J/??+?-. No significant ...
Measurement of B(J/psi -> eta ' e(+)e(-)) and search for a dark photon
(Amer Physical Soc., 2019)
Using a data sample of (1310.6 +/- 7.0) x 10(6) J/psi decay events collected with the BESIII detector at BEPCII, we study the electromagnetic Dalitz decay J/psi -> eta ' e(+)e(-) with two dominant eta' decay modes, eta' ...
Study of eta(1475) and X(1835) in radiative J/psi decays to gamma phi
(Amer Physical Soc., 2018)
The decay J/psi -> gamma gamma phi is studied using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector. Two structures around 1475 MeV/c(2) and 1835 MeV/c(2) are observed in the gamma phi invariant ...
Fabrication of naturel pumice/ hydroxyapatite composite for biomedical engineering
(BioMed Central, 2016)
Background: We evaluated the Bovine hydroxyapatite (BHA) structure. BHA powder was admixed with 5 and 10 wt% natural pumice (NP). Compression strength, Vickers micro hardness, Fourier transform infrared spectroscopy, ...
Determination of the Pseudoscalar Decay Constant f(Ds)(+) via D-s(+) -> mu(+)nu(mu)
(Amer Physic Soc., 2019)
Using a 3.19 fb(-1) data sample collected at an e(+)e(-) center-of-mass energy of E-cm = 4.178 GeV with the BESIII detector, we measure the branching fraction of the leptonic decay D-s(+) -> mu(+)nu(mu) to be BDs+ -> mu+nu ...
