We review the compactification to five‐dimensional heterotic M‐theory on a Schoen Calabi–Yau threefold and the specific SU(4) vector bundle leading to the “heterotic standard model” in the observable sector. Within strongly coupled heterotic M‐theory, a formalism for consistent hidden‐sector bundles associated with a single line bundle is presented, and a specific line bundle is introduced as a concrete example. Anomaly cancellation and the associated bulk space five‐branes are discussed in… 

Explicit soft supersymmetry breaking in the heterotic M-theory B − L MSSM

The strongly coupled heterotic M-theory vacuum for both the observable and hidden sectors of the B − L MSSM theory is reviewed, including a discussion of the “bundle” constraints that both the

Moduli and Hidden Matter in Heterotic M-Theory with an Anomalous $U(1)$ Hidden Sector

This paper discusses the dilaton, Kähler moduli and hidden sector matter chiral superfields of heterotic M -theory vacua in which the hidden sector gauge bundle is chosen to be a line bundle with an

FIMP dark matter in heterotic M-theory

Abstract Within the context of N = 1 supersymmetric heterotic M-theory, we present a “freeze-in” mechanism for producing dark matter via a “moduli portal” between the observable and hidden sectors.

Heterotic $M$-Theory Hidden Sectors with an Anomalous $U(1)$ Gauge Symmetry

The hidden sector of heterotic M -theory vacua whose gauge bundle contains an anomalous U(1) factor is discussed in detail. The mathematical formalism for computing the inhomogeneous transformation

Twistorial cohomotopy implies Green–Schwarz anomaly cancellation

We characterize the integral cohomology and the rational homotopy type of the maximal Borel-equivariantization of the combined Hopf/twistor fibration, and find that subtle relations satisfied by the



Vacuum Constraints for Realistic Strongly Coupled Heterotic M-Theories

The compactification from the 11-dimensional Horava-Witten orbifold to 5-dimensional heterotic M-theory on a Schoen Calabi-Yau threefold is reviewed, as is the specific S U ( 4 ) vector bundle

Supersymmetric hidden sectors for heterotic standard models

A bstractWithin the context of the weakly coupled E8 × E8 heterotic string, we study the hidden sector of heterotic standard model compactifications to four-dimensions. Specifically, we present a

Compactifications of the heterotic string with unitary bundles

We describe a large new class of four‐dimensional supersymmetric string vacua defined as compactifications of the E8 × E8 and the SO(32) heterotic string on smooth Calabi‐Yau threefolds with unitary

Loop-corrected compactifications of the heterotic string with line bundles

We consider the E 8 ? E 8 heterotic string theory compactified on Calabi-Yau manifolds with bundles containing abelian factors in their structure group. Generic low energy consequences such as the

Five-brane BPS states in heterotic M-theory

We present explicit methods for computing the discriminant curves and the associated Kodaira type fiber degeneracies of elliptically fibered Calabi-Yau threefolds. These methods are applied to a

Phenomenological implications of the volume of the Calabi-Yau threefolds on the hidden and observable M-theory boundaries, together with slope stability of their corresponding vector bundles,

Aspects of branes in (heterotic) M-theory

First a short introduction to principles and some recent developments in string theory is given. In a second part the effective action for fiveas well as four-dimensional heterotic M-theory in the

We construct heterotic standard models by compactifying on smooth Calabi-Yau three-folds in the presence of purely Abelian internal gauge fields. A systematic search over complete intersection
