Extra Dimensional Metric Reversal Symmetry and Its Prospect for Cosmological Constant and Zero-Point Energy Problems, Automatic Pauli-Villars 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.
