Abstract

A new strong interaction sector is proposed as a possible origin for the Dark Energy and Dark matter. It is described by an unbroken gauge group SU(2)Z which grows strong at a scale ΛZ 10-3 eV provided its coupling is of the order of the electroweak coupling at some high energy scale (either 1016 GeV or O(TeV) . The present vacuum energy which is consistent with a cosmological constant is related to ΛZ and one of the SU(2)Z ``matter fields'' provides a candidate for the Dark Matter in the form of a weakly interacting massive particle (WIMP) with an annihilation cross section naturally of the order of the electroweak one at the time of its decoupling.
