Contribution
It reviews methods for determining positivity domains and provides typical examples in spin-dependent reactions, highlighting the importance of positivity in spin physics.
Findings
Positivity constrains spin observable domains.
Methods for determining positivity domains are summarized.
Examples illustrate the impact of positivity constraints.
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.
