Unitarity and Entropy Change in Exclusive Quark Combination Models
arXiv:1005.4664
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 rôle that guarantees the non-decrease of the entropy in the exclusive combination process.
