Vector supersymmetry of the superstring in the super-Beltrami parametrization

A. Boresch, M. Schweda, S. P. Sorella

The vector supersymmetry recently found for the bosonic string is generalized to superstring theories quantized in the super-Beltrami parametrization.

Distributional Energy-Momentum Tensor of the Kerr-Newman Space-Time Family

Herbert Balasin, Herbert Nachbagauer

Using the Kerr-Schild decomposition of the metric tensor that employs the algebraically special nature of the Kerr-Newman space-time family, we calculate the energy-momentum tensor…

Baryon-Baryon Potentials on the Lattice

K. Rabitsch, H. Markum, W. Sakuler

The interaction of spatially extended heavy baryons is investigated in the framework of lattice QCD with dynamical quarks. It is shown that the expected dipole forces have a very s…

Two-Dimensional Lattice Gravity as a Spin System

W. Beirl, H. Markum, J. Riedler

Quantum gravity is studied in the path integral formulation applying the Regge calculus. Restricting the quadratic link lengths of the originally triangular lattice the path integr…

Two-Point Functions of Four-Dimensional Simplicial Quantum Gravity

W. Beirl, H. Markum, J. Riedler

We investigate the interaction mechanism of pure quantum gravity in Regge discretization. We compute volume-volume and link-link correlation functions. In a preliminary analysis th…

On the existence of a first order phase transition at small vacuum angle in the model

S. Olejnik, G. Schierholz

We examine the phase structure of the model as a function of in the weak coupling regime. It is shown that the model has a first order phase transition at small . We…
