Non-Kähler string backgrounds and their five torsion classes

- G. Cardoso, G. Curio, G. Dall’Agata, D. Lust, P. Manousselis, G. Zoupanos
- Physics, Mathematics
- 13 November 2002

We discuss the mathematical properties of six-dimensional non-Kahler manifolds which occur in the context of N=1 supersymmetric heterotic and type IIA string compactifications with non-vanishing… Expand

Intersecting branes and a standard model realization in matrix models

- 1 July 2011

We consider intersecting brane solutions of the type IIB matrix model. It is shown that fermionic zero-modes arise on such backgrounds, localized at the brane intersections. They lead to chiral… Expand

Dimensional reduction over fuzzy coset spaces

- Physics
- 8 October 2003

We examine gauge theories on Minkowski space-time times fuzzy coset spaces. This means that the extra space dimensions instead of being a continuous coset space S/R are a corresponding finite matrix… Expand

Coset space dimensional reduction of gauge theories

- D. Kapetanakis, G. Zoupanos
- Physics
- 1 October 1992

A very interesting approach in the attempts to unify all the interactions is to consider that a .unification takes place in higher than four dimensions. The most ambitious program based on the old… Expand

Further all-loop results in softly-broken supersymmetric gauge theories

- 7 February 1998

Abstract It is proven that the recently found, renormalization-group invariant sum rule for the soft scalar masses in softly-broken N =1 supersymmetric gauge-Yukawa unified theories can be extended… Expand

Dynamical generation of fuzzy extra dimensions, dimensional reduction and symmetry breaking

- P. Aschieri, T. Grammatikopoulos, H. Steinacker, G. Zoupanos
- Physics
- 2 June 2006

We present a renormalizable 4-dimensional SU(N) gauge theory with a suitable multiplet of scalar fields, which dynamically develops extra dimensions in the form of a fuzzy sphere S 2 N . We… Expand

On the fermion spectrum of spontaneously generated fuzzy extra dimensions with fluxes

- A. Chatzistavrakidis, H. Steinacker, G. Zoupanos
- Physics
- 30 September 2009

We consider certain vacua of four-dimensional SU(N) gauge theory with the same field content as the N = 4 supersymmetric Yang-Mills theory, resulting from potentials which break the N = 4… Expand

Dimensional reduction of the heterotic string over nearly-Kähler manifolds

- A. Chatzistavrakidis, G. Zoupanos
- Physics
- 14 May 2009

Our aim is to derive the effective action in four dimensions resulting by reducing dimensionally the ten-dimensional = 1 heterotic supergravity coupled to = 1 super Yang-Mills over manifolds… Expand

Supersymmetric compactifications of heterotic strings with fluxes and condensates

- P. Manousselis, N. Prezas, G. Zoupanos
- Physics
- 10 November 2005

Abstract We discuss supersymmetric compactifications of heterotic strings in the presence of H-flux and general condensates using the formalism of G -structures and intrinsic torsion. We revisit the… Expand

Dimensional reduction of ten-dimensional supersymmetric gauge theories in the = 1, D = 4 superfield formalism

- P. Manousselis, G. Zoupanos
- Physics
- 19 June 2004

A ten-dimensional supersymmetric gauge theory is written in terms of = 1, D = 4 superfields. The theory is dimensionally reduced over six-dimensional coset spaces. We find that the resulting… Expand
