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 ??
(2014)
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 ...
Assessment of right ventricular systolic and diastolic parameters in pulmonary sarcoidosis
(BMJ Journals, 2016)
The clinical manifestations of cardiac involvement are seen in about 5% of patients with sarcoidosis; however, the incidence of cardiac involvement is higher in the autopsy series. About 14% of patients with pulmonary ...
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 ...
Observation of D+ -> f(0) (500)e(+) nu(e) and Improved Measurements of D -> rho e(+) nu(e)
(Amer Physic Soc., 2019)
Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) recorded by the BESIII detector at a center-of-mass energy of 3.773 GeV, we present an analysis of the decays D-0 -> pi(-) pi(0) e(vertical bar) ...
