Higgs Mass Prediction for Realistic String/M Theory Vacua

TL;DR

This paper predicts the Higgs boson mass within a specific range based on string/M-theory vacua that satisfy cosmological constraints, providing a link between fundamental theory and observable particle physics.

Contribution

It offers a robust prediction of the Higgs mass range in realistic string/M-theory models with MSSM matter content, connecting high-energy theory to experimental data.

Findings

Higgs mass predicted between 105 GeV and 129 GeV.

For tan beta > 7, Higgs mass range narrows to 122-129 GeV.

Predictions are robust under mild assumptions in string/M-theory frameworks.

Abstract

Recently it has been recognized that in compactified string/M-theories that satisfy cosmological constraints, it is possible to derive some robust and generic predictions for particle physics and cosmology with very mild assumptions. When the matter and gauge content below the compactification scale is that of the MSSM, it is possible to make precise predictions. In this case, we predict that there will be a single Standard Model-like Higgs boson with a calculable mass 105 GeV $\lesssim M_h \lesssim$ 129 GeV depending on tan beta (the ratio of the Higgs vevs in the MSSM). For tan beta > 7, the prediction is : 122 GeV $\lesssim M_h \lesssim$ 129 GeV.
