TL;DR
This paper discusses how positivity constraints limit the possible values of spin observables in various particle reactions, providing specific examples in strangeness exchange and photoproduction.
Contribution
It introduces the application of positivity constraints to define the allowed domains of spin observables in different reactions, offering new insights into their interrelations.
Findings
Positivity constrains spin observable domains.
Examples provided for strangeness-exchange reactions.
Applications shown in photoproduction processes.
Abstract
Positivity constrains the allowed domain for sets of spin observables in exclusive or inclusive reactions. Examples are given for strangeness-echange reactions and photoproduction.
