From Extended Gravity with Torsion-Spin Coupling to Running Constant for Weak-Leptonic Forces

TL;DR

This paper demonstrates how extending gravity with torsion leads to fermion interactions that mimic the weak leptonic forces, with coupling strengths that vary with energy.

Contribution

It introduces a natural extension of gravity with torsion that results in running couplings for fermion interactions resembling weak leptonic forces.

Findings

Fermion fields acquire energy-dependent couplings.

The model reproduces the structure of weak leptonic interactions.

Coupling constants run with energy in the extended gravity framework.

Abstract

In this paper we show how in the most natural extension of gravity with torsion, fermion fields are endowed with running coupling in spinorial interaction, that are shown to reproduce the strength and structure of the leptonic weak forces.
