17. Recent Progress of Geant4 Electromagnetic Physics and Readiness for the LHC Start

Prof. Vladimir Ivantchenko (CERN, ESA)

3. Computation in Theoretical Physics

Parallel Talk

The status of Geant4 electromagnetic (EM) physics models is presented, focusing on the models most relevant for collider HEP experiments, at LHC in particular. Recently improvements were undertaken in models for the transport of electrons and positrons, and for hadrons. Models revised included those for single and multiple scattering, ionization at low and high energies, bremsstrahlung,...

Parallel Talk

Two types of SANC system output are presented. At first the status of stand-alone packages for calculations of the EW and QCD NLO RC at the parton level (Standard SANC FORM and/or FORTRAN Modules) are done. Short overview of these packages in sector of the Neutral Current: (uu, dd) -> (mu,mu, ee) and ee(uu, dd) -> HZ; and in the sector of the Charge Current: ee(uu, dd) -> (mu nu_mu, e...

3. Computation in Theoretical Physics

Parallel Talk

Dynamics of two bodies, which interacts by magnetic forces, is considered. Model of interaction builds on quasi-stationary approach for electromagnetic field, and symmetric rotors with different moments of inertia of the bodies are considered. Interaction energy general form is discovered for the case of coincidence of mass and magnetic symmetries. Since the energy of interaction depends only...
