Unitary symmetry of DDK sum rules for hadron photoproduction on octet baryons

TL;DR

This paper demonstrates that DDK sum rules for hadron photoproduction on octet baryons can be explained using a unitary symmetry approach, simplifying the relations to depend on only three parameters.

Contribution

It introduces a unitary symmetry framework to interpret DDK sum rules, reducing their complexity to three key parameters.

Findings

Sum rules can be expressed with only three parameters.

Integrals over cross-section differences align with symmetry predictions.

Provides a unified understanding of photoproduction sum rules.

Abstract

Dubnicka-Dubnickova-Kuraev (DDK) sum rules are considered. It is shown that integrals over differences of the total photoproduction cross-sections on octet baryons could be understood in terms of unitary symmetry approach. All the DDK sum rules for these quantities are expressed in terms of only three parameters.
