A survey of atomic binding energies used by general purpose Monte Carlo systems is reported. Various compilations these parameters have been evaluated; their accuracy estimated with respect to experimental data. Their effects on physical quantities relevant particle transport are highlighted: X-ray fluorescence emission, electron and proton ionization cross sections, Doppler broadening in Compton scattering. The due different quantified Among the examined compilations, EADL found a less...

We present a new measurement of the production cross section $\sigma(p\bar{p} \rightarrow ZZ)$ at center-of-mass energy $\sqrt{s}=1.96$ TeV, obtained from analysis four charged lepton final state $\ell^{+}\ell^{-}\ell^{'+} \ell^{'-}$ ($\ell$, $\ell^{'}$ = $e$ or $\mu$). observe ten candidate events with an expected background $0.37 \pm 0.13$ events. The measured \to ZZ)= 1.26^{+0.47}_{-0.37} \mathrm{(stat)} 0.14 \mathrm{(syst)}$ pb is in agreement NLO QCD predictions. This result combined...

The Geant4 toolkit offers a rich variety of electromagnetic physics models; so far the evaluation this domain has been mostly focused on its functionality, while features design and their impact simulation accuracy, computational performance facilities for verification validation have not object comparable attention yet, despite critical role they play in many experimental applications. A new project is progress to study application concepts software techniques physics, evaluate how can...
