A Two-Dimensional Four-Quadrant Geometric UnifiedParticle Model: A CompleteTheory Derivedfrom Dimensional Reduction of the Four Dimensional Tesseract

Based on the dimensional reduction of the tesseract, this paper establishes a 2D four-quadrant geometric unified particle model, focusing on the geometric unification of elementary particles, quantum phenomena and dark matter. By defining the chirality and material properties of the four quadrants, using four basic geometric curves to describe elementary particles and quantum effects, the model constructs a complete particle system, clarifies the space-time and chirality relationships between the mirror universe and the material universe, and explains the physical nature and action mechanism of dark matter, providing a new theoretical framework for related physical research. Note: The keywords are all derived from the core research content of the paper, covering four major physical research directions: high-dimensional geometric basis, particle physics, quantum phenomena, and cosmology. They are concise and suitable for English paper submission standards, which can be directly used in the keyword section of the paper. The brief English introduction accurately summarizes the core content of the paper, which is concise and rigorous, suitable for auxiliary instructions such as paper abstract extension or submission.
