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…

Constraining P and CP violation in the main decay of the neutral Sigma hyperon

Shankar Sunil Nair, Elisabetta Perotti, Stefan Leupold

On general grounds based on quantum field theory the decay amplitude for $Σ^{0} \to Λ γ$ consists of a parity conserving magnetic and a parity violating electric dipole transition mom…
