Idea

In particle physics the letters MSSM are an abbreviation for “minimally supersymmetric standard model”: an extension of the standard model of particle physics to a model (in particle phyiscs) with a minimum amount of extra global supersymmetry.

In heterotic string theory

The origin of all string phenomenology is the top-down approach in the heterotic string due to (Candelas-Horowitz-Strominger-Witten 85).

A brief review of motivations for GUT models in heterotic string theory is in

The following articles establish the existences of exact realization of the gauge group and matter-content of the MSSM in heterotic string theory (not yet checking Yukawa couplings):

A computer search through the “landscape” of Calabi-Yau varieties showed several hundreds more such exact heterotic standard models (about one billionth of all CYs searched, and most of them arising as SU(5)SU(5)-GUTs)

The resulting database of compactifications is here:

Review includes

Computation of metrics on these Calabi-Yau compactifications (eventually needed for computing their induced Yukawa couplings) is started in

This “heterotic standard model” has a “hidden sector” copy of the actual standard model, more details of which are discussed here:

The issue of moduli stabilization in these kinds of models is discussed in

Principles singling out heterotic models with three generations of fundamental particles are discussed in:
