We present measurements of the tWb coupling form factors using information from electroweak single top quark production and helicity W bosons decays in ttbar events. set upper limits on anomalous data collected with D0 detector at Tevatron ppbar collider corresponding to an integrated luminosity 5.4 fb^-1.
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...
A set of physics models and parameters pertaining to the simulation proton energy deposition in matter are evaluated range up approximately 65 MeV, based on their implementations Geant4 toolkit.The analysis assesses several features impact associated epistemic uncertainties, i.e. uncertainties due lack knowledge, results.Possible systematic effects deriving from this kind highlighted; relevance relation application environment different experimental requirements discussed, with emphasis...
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...
A R&D project has been recently launched to investigate Geant4 architectural design in view of addressing new experimental issues HEP and other related physics disciplines. In the context this use generic programming techniques besides conventional object oriented is investigated. Software features preliminary results from a prototype implementation electromagnetic are illustrated. Performance evaluations presented. Issues quality assurance modelling discussed.
A R&D project has been launched in 2009 to address fundamental methods radiation transport simulation and revisit Geant4 kernel design cope with new experimental requirements. The focuses on at different scales the same environment: this set of problems requires across current boundaries condensed-random-walk discrete schemes. An exploration is also foreseen about exploiting extending already existing features apply Monte Carlo deterministic environment. overview associated presented,...
