On weak interactions as short-distance manifestations of gravity

TL;DR

This paper proposes that weak interactions are short-distance effects of quantum gravity, linking the Fermi constant to the Newtonian constant, and suggests gravity's role in microscopic phenomena.

Contribution

It introduces a novel hypothesis that weak interactions originate from quantum gravity effects at the Fermi scale, unifying fundamental forces at short distances.

Findings

Weak interactions may be manifestations of quantum gravity.

Violations of symmetries like parity could stem from spacetime fluctuations.

Experimental tests are proposed to validate this hypothesis.

Abstract

We conjecture that weak interactions are peculiar manifestations of quantum gravity at the Fermi scale, and that the Fermi constant is related to the Newtonian constant of gravitation.In this framework one may understand the violations of fundamental symmetries by the weak interactions, in particular parity violations, as due to fluctuations of the spacetime geometry at a Planck scale coinciding with the Fermi scale. As a consequence, gravitational phenomena should play a more important role in the microworld, and experimental settings are suggested to test this hypothesis.
