Spin effects for high energy binary processes at large angles
- Bogoliubov Laboratory of Theoretical Physics, Joint Institute for Nuclear Research, Dubna 141980 (Russia)
We consider spin asymmetries for two concrete reactions (proton-proton elastic scattering and proton antiproton annihilation into photino and antiphotino) on the basis of general formalism for description of any binary processes with particles of arbitrary spins and masses. In a formalism provides an analysis where spin-kinematics is fully taken into account and clearly separated from dynamics. In this {open_quote}{open_quote}dynamic amplitude{close_quote}{close_quote} approach obligatory kinematic factors arise in the expressions of observables. These spin structures for high energies give a small parameter that orders the contributions of helicity amplitudes to observables. This results in hierarchy of amplitude contributions, connections between asymmetry parameters and even numerical values for some of them. {copyright} {ital 1995 American Institute of Physics.}
