Induced gravity and gauge interactions revisited

TL;DR

This paper revisits Sakharov's induced gravity and gauge interactions, demonstrating their phenomenological viability, examining the role of UV cutoff, and showing that induced gauge couplings align with realistic values.

Contribution

It provides a comprehensive analysis of induced gravity and gauge interactions, including the role of UV cutoff and black hole entropy as tools for validation.

Findings

Induced gravity and gauge interactions yield phenomenologically reasonable results.

The UV cutoff plays a significant role in the induced gravity framework.

Induced gauge couplings of the standard model are qualitatively realistic.

Abstract

It has been shown that the primary, old-fashioned idea of Sakharov's induced gravity and gauge interactions, in the "one-loop dominance" version, works astonishingly well yielding phenomenologically reasonable results. As a byproduct, the issue of the role of the UV cutoff in the context of the induced gravity has been reexamined (an idea of self-cutoff induced gravity). As an additional check, the black hole entropy has been used in the place of the action. Finally, it has been explicitly shown that the induced coupling constants of gauge interactions of the standard model assume qualitatively realistic values.
