 Title: On polarization parameters of spin-1 particles and anomalous
 triple gauge boson couplings


 Abstract:

 A spin-1 particle (Z , W± ) has 8 polarization observables, which
 can be extracted from the decay angular distribution of the particle at
 collider. These spin-polarization observables of a gauge boson along
 with
 the production cross section can be used to study the anomalous gauge
 boson couplings. We studied anomalous gauge boson self coupling in
 e+ e− -> ZZ /Z gamma and e+ e− -> W+ W− with and without polarized
 beams
 and obtained constrained on the anomalous couplings using production
 cross section and spin polarization of Z, W± .
