Polarization observables in the $e^{+}e^{-} \rightarrow \bar{\Lambda}\Lambda$ reaction

Polarization Observables and High Momenta in the Deuteron Wave Function

One–loop corrections to polarization observables

We review the physics of polarization observables in high energy reactions in general and discuss the status of NLO one–loop corrections to these observables in specific. Many high order radiative corrections exists for rates but not many NLO radiative corrections exist for polarization observables. The radiative correction calculations for polarization observables are somewhat more complicated...

Classifying Polarization Observables of the Cosmic Microwave Background

We revisit the classification of polarization observables of the cosmic microwave background. There exists a unified approach to the 3 × 3 density matrix by which intensity, linear and circular polarization are treated on an equal footing. The representations of the rotation group on the sphere contain certain right-left setup symmetries which have not been taken into account before. Left-right...

Gluon Polarization in ee → tt̄G: Polar Angle Dependence and Beam Polarization Effects

We calculate the linear and circular polarization of gluons produced in conjunction with massive quarks in the annihilation process e+e− → qq̄G. The linear polarization is calculated in the hadron event plane as well as in the gluon-beam plane. Beam polarization and polar orientation effects are included in our discussion. For typical top pair production energies at the Next-Linear-Collider (NLC...

Meson-exchange currents in „e ,e8p... recoil polarization observables

A study of the effects of meson-exchange currents and isobar configurations in A(eW ,e8pW )B reactions is presented. We use a distorted wave impulse approximation model where final-state interactions are treated through a phenomenological optical potential. The model includes relativistic corrections in the kinematics and in the electromagnetic oneand two-body currents. The full set of polarize...
