Is there a new physics between electroweak and Planck scales?

TL;DR

This paper explores the possibility that no new physics exists between the electroweak and Planck scales, suggesting solutions to Standard Model problems could occur at these scales without intermediate particles.

Contribution

It proposes a paradigm where the energy gap between the electroweak and Planck scales contains no new particles, challenging traditional expectations of intermediate-scale physics.

Findings

No intermediate scale of new particles between electroweak and Planck scales.

Standard Model problems could be addressed at either the electroweak or Planck scale.

Experimental predictions are outlined for this scenario.

Abstract

We argue that there may be no intermediate particle physics energy scale between the Planck mass $M_{Pl}\sim 10^{19}$ GeV and the electroweak scale $M_W \sim 100$ GeV. At the same time, the number of problems of the Standard Model (neutrino masses and oscillations, dark matter, baryon asymmetry of the Universe, strong CP-problem, gauge coupling unification, inflation) could find their solution at $M_{Pl}$ or $M_W$. The crucial experimental predictions of this point of view are outlined.
