Extra dimensional metric reversal symmetry and its prospect for cosmological constant and zero-point energy problems, automatic pauli-villars-like regularization, and an interesting kaluza-klein spectrum

Abstract

The metric reversal symmetry was introduced in the context of cosmological constant problem. Besides proposing a solution to the cosmological constant problem the metric reversal symmetry has also provided a framework for solution of the zero-point energy problem, an automatic Pauli-Villars-like regularization, and an interesting Kaluza- Klein spectrum with interesting phenomenological implications. In this talk I give a brief overall summary and discussion of these topics with their potential implications.
