Spin Density Matrix For Spin-3/2 Particles

Jiao Jiao Song, Wan Ling Chang

The description of particles with spin can be attained by using a spin density matrix in high energy reaction. In this paper we present a parametrization of the spin density matrix…

Polarization observables in $e^{+} e^{-}$ annihilation to a baryon-antibaryon pair

Elisabetta Perotti, Göran Fäldt, Andrzej Kupść +2

Using the helicity formalism of Jacob and Wick we derive spin density matrices of baryon antibaryon pairs produced in $e^{+} e^{-}$ annihilation. We consider the production of pairs wit…
