A Family of N=1 SU(N)^k Theories from Branes at Singularities

E. Lopez

We obtain N=1 SU(N)^k gauge theories with bifundamental matter and a quartic superpotential as the low energy theory on D3-branes at singular points. These theories generalize that…

Effective action and Hawking radiation for dilaton coupled scalars in two dimensions

W. Kummer, D. V. Vassilevich

The effective one-loop action for general dilaton theories with arbitrary dilaton-dependent measure and nonminimal coupling to scalar matter is computed. As an application we deter…

Tensorial Central Charges and New Superparticle Models with Fundamental Spinor Coordinates

Igor Bandos, Jerzy Lukierski

We consider firstly simple D=4 superalgebra with six real tensorial central charges , and discuss its possible realizations in massive and massless cases. Massless case is…

Two-Dimensional Bosonization from Variable Shifts in the Path Integral

Jan B. Thomassen

A method to perform bosonization of a fermionic theory in (1+1) dimensions in a path integral framework is developed. The method relies exclusively on the path integral property of…

Confinement potential in dual Monopole Nambu-Jona-Lasinio model with dual Dirac strings

M. Faber, A. N. Ivanov, A. Mueller +2

Interquark confinement potential is calculated in the dual Monopole Nambu-Jona-Lasinio model with dual Dirac strings as a functional of a dual Dirac string length. The calculation…

Integrating Geometry in General 2D Dilaton Gravity with Matter

W. Kummer, H. Liebl, D. V. Vassilevich

General 2d dilaton theories, containing spherically symmetric gravity and hence the Schwarzschild black hole as a special case, are quantized by an exact path integral of their geo…
