A Unified PT-Even Torsion Framework for the Dark Sector: Cosmology, Galaxies, and Collider Signatures

2026-02-04

Abstract excerpt

We present a four-dimensional, PT-symmetric quaternion-inspired extension of General Relativity formulated in a PT-even Palatini posture. Rather than treating a quaternionic "imaginary metric" as a physical spacetime tensor, we define the physical sector by a PT-even projection operator $\Pi_{PT}$ acting on the action and on composite observables:$$S_{phys} \equiv \Pi_{PT} [S(g, \Gamma, \phi; \epsilon)]$$ so that...
