"Low" Energy GUTs

TL;DR

This paper proposes a new approach to grand unification that lowers the GUT scale to around 200 TeV, making it potentially testable with future laboratory colliders by suppressing baryon number violation effects.

Contribution

It introduces a novel method inspired by heterotic string symmetry to achieve a low GUT scale while keeping baryon number violation effects undetectably small.

Findings

GUT scale can be as low as 200 TeV.

Baryon number violation effects are suppressed.

Potential for experimental tests at future colliders.

Abstract

We introduce a new approach to the subject of grand unification which allows the GUT scale to be small, \lesssim 200 TeV, so that it is within the reach of {\em conceivable} laboratory accelerated colliding beam devices. Central to the approach is a novel abstraction of the heterotic string symmetry group physics ideas to render baryon number violating effects small enough to have escaped detection to date.
