Gauge fields and interactions in matrix string theory

Thomas Wynter

It is shown that all possible N sheeted coverings of the cylinder are contained in type IIA matrix string theory as non-trivial gauge field configurations. Using these gauge field…

Open Supermembranes Coupled to M-Theory Five-Branes

Ph. Brax, J. Mourad

We consider open supermembranes in eleven dimensions in the presence of closed M-Theory five-branes. It has been shown that, in a flat space-time, the world-volume action is kappa…

Generalized Dynkin diagrams and root systems and their folding

Jean-Bernard Zuber

Graphs which generalize the simple or affine Dynkin diagrams are introduced. Each diagram defines a bilinear form on a root system and thus a reflection group. We present some prop…

Exponentially Small Couplings and the Hierarchy Problem

Ph. Brax, Neil Turok

We propose a stringy mechanism whereby a large hierarchy between symmetry breaking scales is generated. This mechanism is based upon the existence of a fifth dimension compactified…

Four-dimensional M-theory and supersymmetry breaking

E. Dudas, C. Grojean

We investigate compactifications of M-theory from dimensions and discuss geometrical properties of 4-d moduli fields related to the structure of 5-d theory. We study…

Open supermembranes in eleven dimensions

Ph. Brax, J. Mourad

We consider open supermembranes in an eleven dimensional background. We show that, in a flat space-time, the world-volume action is kappa-symmetric and has global space-time supers…

Systematics of string loop threshold corrections in orbifold models

Marc Chemtob

String theory one-loop threshold corrections are studied in a background field approach due to Kiritsis and Kounnas which uses space-time curvature as an infrared regulator. We rev…

Complex Matrix Models and Statistics of Branched Coverings of 2D Surfaces

Ivan K. Kostov, Matthias Staudacher, Thomas Wynter

We present a complex matrix gauge model defined on an arbitrary two-dimensional orientable lattice. We rewrite the model's partition function in terms of a sum over representations…

SU(N) Meander Determinants

P. Di Francesco

We propose a generalization of meanders, i.e., configurations of non-selfintersecting loops crossing a line through a given number of points, to SU(N). This uses the reformulation…

Field-Theoretic Techniques in the Study of Critical Phenomena

C. Bagnuls, C. Bervillier

We shortly illustrate how the field-theoretic approach to critical phenomena takes place in the more complete Wilson theory of renormalization and qualitatively discuss its domain…

Some Properties of the Calogero-Sutherland Model with Reflections

D. Serban

We prove that the Calogero-Sutherland Model with reflections (the BC_N model) possesses a property of duality relating the eigenfunctions of two Hamiltonians with different couplin…
