# On the Role of Einstein-Cartan Gravity in Fundamental Particle Physics

## TL;DR

This paper explores how Einstein-Cartan gravity, through the Hehl-Datta equation, may explain the low mass of elementary fermions and the energy balance near the Planck scale, offering a new perspective in particle physics.

## Contribution

It introduces a novel mechanism from ECSK gravity that potentially explains fermion mass and energy balance at the Planck scale.

## Key findings

- Gravity-induced self-interaction can account for low fermion masses.
- Mechanism addresses divergence of electrostatic and strong force energies.
- Numerical estimates support the proposed explanation.

## Abstract

Two of the major open questions in particle physics are: (1) Why are the elementary fermionic particles that are so far observed have such low mass-energy compared to the Planck energy scale? And (2), what mechanical energy may be counterbalancing the divergent electrostatic and strong force energies of point-like charged fermions in the vicinity of the Planck scale? In this paper, using a hitherto unrecognized mechanism derived from the non-linear amelioration of Dirac equation known as the Hehl-Datta equation within Einstein-Cartan-Sciama-Kibble (ECSK) extension of general relativity, we present detailed numerical estimates suggesting that the mechanical energy arising from the gravity-induced self-interaction in the ECSK theory can address both of these questions in tandem.
