Electron-atom bremsstrahlung: double differential cross section and polarization correlations
Electron-atom bremsstrahlung double differential cross section polarization correlations
2010/11/16
The leading-order electron-atom bremsstrahlung is investigated within the rigorous relativistic approach based on the partial-wave representation of the Dirac wave functions in the external atomic fi...
Leading-Order Determination of the Gluon Polarization from high-$p_T$ Hadron Electroproduction
Lepton-Nucleon Scattering Deep Inelastic Scattering QCD gluon polarization
2010/3/15
Longitudinal double-spin asymmetries of charged hadrons with high transverse momentum $p_T$ have been measured in electroproduction using the \hermes\ detector at \hera. Processes involving gluons in ...
Vacuum Polarization Effects in Relativistic Nuclear Pairing
Vacuum Polarization Effects Relativistic Nuclear Pairing
2010/10/25
In the present work we discuss the contribution of the vacuum polarization on the nuclear pairing, in the context of the relativistic Hartree-Fock-Bogoliubov (HFB) approximation. The polarization effe...
Antihyperon Polarization in Inclusive Processes at High Energies
Antihyperon Polarization Inclusive Processes High Energies
2010/10/19
We propose a model that we believe is the main source of the antihyperon polarization in high-energy protonnucleus inclusive reactions. The polarization is originated by the final-state interactions b...
