The heterotic MiniLandscape and the 126 GeV Higgs boson

TL;DR

This paper explores heterotic MiniLandscape models predicting a constrained supersymmetry breaking pattern, light stops, and a Higgs mass consistent with observations, with implications for future dark matter detection.

Contribution

It introduces a specific heterotic MiniLandscape framework with distinctive gaugino and sfermion mass patterns, reducing fine-tuning and aligning with the 126 GeV Higgs boson.

Findings

Gaugino mass pattern is fully predictable and compressed.

Stops can be as light as 1 TeV due to geometric localisation.

Lower bound on gluino mass is 1.2 TeV based on Higgs mass.

Abstract

The MSSM candidates arising from the heterotic MiniLandscape feature a very constrained supersymmetry breaking pattern. This includes a fully predictable gaugino mass pattern, which is compressed compared to the CMSSM, and an inverted sfermion hierarchy due to distinct geometric localisation, featuring stops as light as 1 TeV. The observed Higgs mass sets a lower bound m_{gluino} > 1.2 TeV on the gluino mass. The electroweak fine-tuning is reduced by a UV relation between the scalar mass of the two heavy families and the gluino mass. While large parts of the favoured parameter space escape detection at the LHC, the prospects to test the MiniLandscape models with future dark matter searches are very promising.
