Polarization observables inγN→KK¯N

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...

Polarization Observables and High Momenta in the Deuteron Wave Function

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...

Weak quasielastic electroproduction of hyperons with polarization observables

With the availability of high luminosity electron beam at the accelerators, there is now the possibility of studying weak quasielastic hyperon production off the proton i.e. ep → νeY (Y = Λ,Σ ), which will enable the determination of nucleon-hyperon vector and axial-vector transition form factors at high Q in the strangeness sector and provide test of the Cabibbo model, G-invariance, CVC, PCAC ...

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...
