Unitarity and Entropy Change in Exclusive Quark Combination Models

TL;DR

This paper demonstrates that the unitarity principle in exclusive quark combination models ensures entropy does not decrease during the process, linking fundamental principles to entropy behavior.

Contribution

It establishes the central role of unitarity in guaranteeing non-decreasing entropy in exclusive quark combination models, connecting fundamental physics principles.

Findings

Unitarity guarantees non-decrease of entropy.

Entropy change relates to fundamental principles.

Exclusive quark combination models adhere to unitarity.

Abstract

Entropy change in exclusive quark combination models is not an isolated problem. Contrary to adding and tuning some parameters to the relevant model(s) to fix the entropy, we show that it relates to the most general principles. Unitarity of the combination model is demonstrated to play the central r\^{o}le that guarantees the non-decrease of the entropy in the exclusive combination process.
