Z_{12-I} Orbifold Compactification toward SUSY Standard Model

TL;DR

This paper explores a specific string theory compactification, Z_{12-I} orbifold, to develop supersymmetric standard models and identifies an effective R-parity, ensuring phenomenological viability.

Contribution

It introduces a Z_{12-I} orbifold compactification approach that yields supersymmetric standard models with an effective R-parity from string theory.

Findings

Successful construction of a SUSY standard model from Z_{12-I} orbifold.

Identification of an effective R-parity in the string model.

Phenomenological constraints satisfied by gauge singlet VEVs.

Abstract

We explain the orbifold compactification in string models and present a Z_{12-I} orbifold compactification toward supersymmetric standard models. We also point out an effective R-parity from this string construction. The VEVs of gauge singlets are chosen such that phenomenological constraints are satisfied.
