"Table 1" of "Ground and excited charmonium state production in p+p collisions at sqrt(s)=200 GeV"
2023
Foreground, background counts in the $J/\psi$ mass region, and the signal count.
"Table 15a" of "Ground and excited charmonium state production in p+p collisions at sqrt(s)=200 GeV"
2023
$J/\psi$ counts obtained from the dimuon decay analysis of four different data sets, determined using the fit function. The S and N following 2006 and 2008 indicate the data sets for the south and north forward arms.

Transverse momentum dependence of $J/\psi$ and $\psi^{\prime}$ yields in $|y|$ < 0.35, and ${\psi^{\prime}}/{J/\psi}$ ratio together with ratios obtained in other experiments. Uncertainties are point-to-point uncorrelated (uncorr.) (statistical and uncorrelated systematic uncertainties) and correlated systematic (corr.) uncertainties. The global uncertainty is 10%.

$\psi^{\prime}(J/\psi)$ dielectron yield ratio measured at $|y|$ < 0.35 followed by point-to-point uncorrelated (uncorr.) (statistical and uncorrelated systematic uncertainties) and correlated systematic (corr.) uncertainties.

Rapidity dependence of the $J/\psi$ yield combining dielectron ($|y|$ < 0.35 - full squares) with dimuon channels (1.2 < $|y|$ < 2.4 - full circles) along with the fits used to estimate the total cross section. Uncertainties are point-to-point uncorrelated (uncorr.) (statistical and uncorrelated systematic uncertainties) and correlated systematic (corr.) uncertainties. The global uncertainty is 10%.

A study of VUV emission and the extracted electron-ion ratio in hydrogen and deuterium plasmas of a filament-driven H−/D− ion source
2019
Vacuum ultraviolet (VUV) emission diagnostics for studying differences of electron impact processes in hydrogen and deuterium plasmas are presented. The method is applied to study a filament driven multicusp arc discharge negative ion source by comparing the VUV-emission intensities of different emission bands and extracted currents of H−/D− ions and electrons. It was found that the ratio of coextracted electrons to extracted ions is four times higher for deuterium than for hydrogen. No significant differences of the VUV-spectra or volumetric rates of ionization, excitation, production of high vibrational states, and dissociation were found between the plasmas of the two isotopes. The volum…
Discharge estimation in natural channels with significant lateral inflow
2015
The indirect measurement technique for discharge estimation, based on water level data analysis in two different river sections, is extended to the case of existing significant tributary flow between the two sections. The methodology is based on the calibration of a numerical flow routing algorithm, solving the Saint-Venant equations in diffusive form along the main channel between the two measurement sections. The first calibration parameter is the average Manning's roughness coefficient holding in the main channel, the other ones are relative to the rating curve of each tributary channel, estimated per unit roughness coefficient and per unit slope immediately before the junction of the tr…
