Mirror Symmetry and Connections between String Theory and Mirror Matter Theory

The newly finished article titled “Mirror symmetry for new physics beyond the Standard Model in 4D spacetime” is going to be recognized as a new milestone on mirror matter studies. In particular, amazing connections between string theory and new supersymmetric mirror models are established. Mirror symmetry as a fundamental concept is deeply examined. The geometrical or mathematical origin of mirror symmetry is from the orientation symmetry of a manifold. T-duality and Calabi-Yau mirror symmetry in string theory are concrete examples or realizations of the more general mirror symmetry in local/compactified spaces. Based on mathematical results from string theory and their reinterpretation under the new framework, we can finally put these mirror models on firmer and self-consistent ground and explain an impressive list of puzzles in fundamental physics and cosmology.
