TL;DR
This paper investigates a specific heterotic orbifold model space, identifying a subset of models that precisely reproduce the MSSM spectrum, highlighting the rarity and characteristics of such models within the landscape.
Contribution
It provides a systematic search for heterotic orbifold models with exact MSSM spectra, revealing their scarcity and specific features.
Findings
Approximately 100 models out of 30,000 satisfy the MSSM spectrum requirement.
The studied orbifold patch contains models with local GUT structures compatible with MSSM.
The results demonstrate the rarity of exact MSSM spectra in this heterotic landscape.
Abstract
We explore a ``fertile patch'' of the heterotic landscape based on a Z_6-II orbifold with SO(10) and E_6 local GUT structures. We search for models allowing for the exact MSSM spectrum. Our result is that of order 100 out of a total 3\times 10^4 inequivalent models satisfy this requirement.
