Lectures on Heterotic M-Theory
Burt A. Ovrut
We present three lectures on heterotic M-theory and a fourth lecture extending this theory to more general orbifolds. In Lecture 1, Horava-Witten theory is briefly discussed. We th…
Four-Dimensional N=1 Super Yang-Mills Theory from an M-Theory Orbifold
Charles F. Doran, Michael Faux, Burt A. Ovrut
Gravitational and gauge anomalies provide stringent constraints on which subset of chiral models can effectively describe M-theory at low energy. In this paper, we explicitly const…
A Brief Comment on "The Pyrotechnic Universe"
Justin Khoury, Burt A. Ovrut, Paul J. Steinhardt +1
We respond to the criticisms by Kallosh, Kofman and Linde concerning our proposal of the ekpyrotic universe scenario. We point out a number of errors in their considerations and ar…
Spectral involutions on rational elliptic surfaces
Ron Donagi, Burt Ovrut, Tony Pantev +1
In this paper we describe a four dimensional family of special rational elliptic surfaces admitting an involution with isolated fixed points. For each surface in this family we cal…
Standard Model Vacua in Heterotic M-Theory
Ron Donagi, Burt A. Ovrut, Tony Pantev +1
We present a class of N=1 supersymmetric ``standard'' models of particle physics, derived directly from heterotic M-theory, that contain three families of chiral quarks and leptons…
Standard Models from Heterotic M-theory
Ron Donagi, Burt A. Ovrut, Tony Pantev +1
We present a class of N=1 supersymmetric models of particle physics, derived directly from heterotic M-theory, that contain three families of chiral quarks and leptons coupled to t…
