Abstract

The expression for the entropy production in the decay of a neutral kaon interacting with a thermal bath of bosons, introduced in a previous article [1], is reformulated without assuming CPT conservation. The relation between the sign of Re ε{lunate} and the thermodynamical arrow of time is further discussed, and the ambiguity due to the definitions of matter-antimatter is resolved.
