Positivity domains for pairs of triples of spin observables

Nuclear Theory 2008-01-17 v1 High Energy Physics - Phenomenology

Abstract

Positivity restrains the allowed domains for pairs or triples of spin observables in polarised reactions. Various domain shapes in 12+1212+12{1\over2}+{1\over2}\to{1\over2}+{1\over2} reactions are displayed. Some methods to determine these domains are mentioned and a new one based on the anticommutation between two observables is presented.
