PREdicted the Higgs Mass

TL;DR

This paper discusses a prediction of the Higgs mass based on the multiple point principle, which suggests the existence of degenerate vacua, and compares it with the observed value, supporting the idea that the Standard Model remains valid up to near the Planck scale.

Contribution

The paper refines the multiple point principle prediction of the Higgs mass and compares it with experimental data, providing support for the Standard Model's validity up to high energy scales.

Findings

Predicted Higgs mass of 129.4 ± 2 GeV closely matches observed 126 ± 1 GeV.

The prediction is based on the concept of degenerate vacua and vacuum stability.

Supports the idea that the Standard Model is valid up to near the Planck scale.

Abstract

We like to investigate the idea of taking as non-accidental a remarkably good agreement of our (C.D. Froggatt and myself, and also with Yasutaka Takanishi) prediction of the Higgs mass. Our modernized most simple "multiple point principle" prediction $129.4 \pm 2$ GeV versus the recently observed $126 \pm 1$ GeV agrees well. The PREdicted Higgs mass is essentially the smallest value, that would not make our present vacuum unstable. There are two slightly different versions in as far as we can either use absolute stability by the alternative vacuum being required to have higher energy density than the present one or just metastability requiring that our vacuum should not have decayed in the early time just after big bang (or later if that should be easier). This is of course provided we suppose that the Standard Model would function almost all the way up to the scale relevant for the alternative vacuum (which as we shall see is close to the Planck energy scale for the Higgs field expectation value). The principle we used to our PREdiction were the requirement of degenerate vacua which we called "multiple point principle" and I shall seek to deliver some arguments that this MPP is "nice" to assume, i.e. it is likely to be true.
