Reducing the Heterotic Supergravity on nearly-Kahler coset spaces (2008)
Chatzistavrakidis, A., Manousselis, P., Zoupanos, G.
We study the dimensional reduction of the ${\cal N}=1$, ten-dimensional Heterotic Supergravity to four dimensions, at leading order in $\alpha'$, when the internal space is a nearly-K\"{a}hler...
Selecting Finite Unified Theories with Current Data (2008)
Heinemeyer, S., Mondragon, M., Zoupanos, G.
Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified Theories that can be made all-loop finite, leading to a severe reduction of the free parameters. We review the investigation of...
Confronting Finite Unified Theories with Low-Energy Phenomenology (2007)
Heinemeyer, S., Mondragon, M., Zoupanos, G.
Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified Theories that can be made all-loop finite. The requirement of all-loop finiteness leads to a severe reduction of the free...
Coset Space Dimensional Reduction of Einstein--Yang--Mills theory (2007)
Chatzistavrakidis, A., Manousselis, P., Prezas, N., Zoupanos, G.
In the present contribution we extend our previous work by considering the coset space dimensional reduction of higher-dimensional Einstein--Yang--Mills theories including scalar fluctuations as well...
The Energy-momentum of a Poisson structure (2007)
Buric, M., Madore, J., Zoupanos, G.
Consider the quasi-commutative approximation to a noncommutative geometry. It is shown that there is a natural map from the resulting Poisson structure to the Riemann curvature of a metric. This map...
Gravity and the Structure of Noncommutative Algebras (2006)
Buric, M., Grammatikopoulos, T., Madore, J., Zoupanos, G.
A gravitational field can be defined in terms of a moving frame, which when made noncommutative yields a preferred basis for a differential calculus. It is conjectured that to a linear perturbation...
Finite SU(N)^k Unification (2004)
Ma, Ernest, Mondragon, Myriam, Zoupanos, G.
We consider N=1 supersymmetric gauge theories based on the group SU(N)_1 x SU(N)_2 x ... x SU(N)_k with matter content (N,N*,1,...,1) + (1,N,N*,...,1) + >... + (N*,1,1,...,N) as candidates for the...
A ten-dimensional supersymmetric gauge theory is written in terms of N=1, D=4 superfields. The theory is dimensionally reduced over six-dimensional coset spaces. We find that the resulting...
Finite Unified Theories and the Higgs mass prediction (2004)
Djouadi, A., Heinemeyer, S., Mondragon, M., Zoupanos, G.
Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified Theories, which can be made all-loop finite, both in the dimensionless (gauge and Yukawa couplings) and dimensionful (soft...
GAUGE-YUKAWA UNIFIED MODELS (1997)
J. Kubo, M. Mondragon, G. Zoupanos
Gauge-Yukawa Unification (GYU) is obtained in GUTs by searching for renormalization group invariant relations among gauge and Yukawa couplings beyond the unification scale. Of particular interest are...
Unification of coupling constants without a covering GUT (1988)
Theisen, Stefan, Tracas, D., Zoupanos, G.
We discuss the possibility of unification of gauge coupling constants of the standard model and its extensions at some high scale without the assuption of the existence of a covering GUT at that...
