Title: The Stueckelberg Extension and Milli Weak and Milli Charged Dark Matter

Abstract

A overview is given of the recent developments in the U(1){sub X} Stueckelberg extensions of the Standard Model and of MSSM where all the Standard Model particles are neutral under the U(1){sub X}, but an axion which is absorbed is charged under both U(1){sub X} and U(1){sub Y} and acts as the connector field coupling the Standard Model sector with the Stueckelberg sector. Coupled with the usual Higgs mechanism that breaks the SU(2){sub L}xU(1){sub Y} gauge symmetry, this scenario produces mixings in the neutral gauge boson sector generating an extra Z{sup '} boson. The couplings of the extra Z{sup '} to the Standard Model particles are milli weak but its couplings to the hidden sector matter, defined as matter that couples only to the gauge field of U(1){sub X}, can be of normal electro-weak strength. It is shown that such extensions, aside from the possibility of leading to a sharp Z{sup '} resonance, lead to two new types of dark matter: milli weak (or extra weak) and milli charged. An analysis of the relic density shows that the WMAP-3 constraints can be satisfied for either of these scenarios. The types of models discussed could arise as possible field point limitmore » of certain Type IIB orientifold string models.« less
