The relevance of positivity in spin physics
arXiv:0906.5165 · doi:10.1063/1.3293879
Abstract
Positivity reduces substantially the allowed domain for spin observables. We briefly recall some methods used to determine these domains and give some typical examples for exclusive and inclusive spin-dependent reactions.
