Q-field from a 4D-brane: Cosmological constant cancellation and Minkowski attractor

Abstract

A 4D-brane realization of $q$-theory has been proposed a few years ago. The present paper studies the corresponding late-time cosmology and establishes the dynamic cancellation of an initial cosmological constant and an attractor behavior towards Minkowski spacetime.
