TL;DR

This paper constructs a Pati-Salam model and a gravity theory on a square root Lorentz manifold, incorporating standard particles, new particles, and a Sheaf quantization approach in curved space-time.

Contribution

It introduces a novel geometric framework using square root Lorentz manifolds to unify Standard Model particles and gravity with Sheaf quantization.

Findings

Standard Model particles and Einstein gravity are embedded in the model.

The gravity theory resembles Einstein-Cartan with torsion.

New particles such as right-handed neutrinos and dark photon are predicted.

Abstract

There is a U(4')\times U(4)-bundle on four-dimensional square root Lorentz manifold. Then a Pati-Salam model in curved space-time (Lagrangian) and a gravity theory (Lagrangian) are constructed on square root Lorentz manifold based on self-parallel transportation principle. An explicit formulation of Sheaf quantization on this square root Lorentz manifold is shown. Sheaf quantization is based on superposition principle and construct a linear Sheaf space in curved space-time. The transition amplitude in path integral quantization is given which is consistent with Sheaf quantization. All particles and fields in Standard Model (SM) of particle physics and Einstein gravity are found in square root metric and the connections of bundle. The interactions between particles/fields are described by Lagrangian explicitly. There are few new physics in this model. The gravity theory is Einstein-Cartan kind with torsion. There are new particles, right handed neutrinos, dark photon, Fiona, X^{\pm C} and Y^0,Y^1,Y^2,Y_*^1,Y_*^2.
