On the cosmological constant, the KK mass scale, and the cut-off dependence in the dark dimension scenario

Abstract

In this short note we comment on the relation between the cosmological and the Kaluza-Klein mass scale in the dark dimension scenario, also in view of some recent claims that would raise some doubts about the validity of this scenario. Here we argue that these claims have serious flaws and cannot be trusted.
