Quantum Models of Black Hole Evaporation
F. Belgiorno, A. S. Cattaneo, F. Fucito +1
The discovery of black-hole evaporation represented in many respects a revolutionary event in scientific world; as such, in giving answers to open questions, it gave rise to new pr…
A Note on the Green - Schwarz Mechanism in Open - String Theories
Augusto Sagnotti
An interesting feature of some open superstring models in is the simultaneous presence, in the spectrum, of gauge fields and of a number of antisymmetric tensor fields. In…
A Conformal Affine Toda Model of 2D Black Holes: A Quantum Study of the Evaporation End-Point
F. Belgiorno, A. S. Cattaneo, M. Martellini +1
In this paper we reformulate the dilaton-gravity theory of Callan \etal\ as a new effective conformal field theory which turns out to be a generalization of the so-called -co…
The U(1)-Higgs Model: Critical Behaviour in the Confinig-Higgs region
Alonso, Azcoiti, Campos +15
We study numerically the critical properties of the U(1)-Higgs lattice model, with fixed Higgs modulus, in the region of small gauge coupling where the Higgs and Confining phases m…
Lattice QCD Spectroscopy with an Improved Wilson Fermion Action
M. -P. Lombardo, G. Parisi, A. Vladikas
We study the hadronic spectrum in quenched lattice QCD using an improved Wilson fermion action (Hamber-Wu(1983),Eguchi-Kawamoto(1984)) at and . We find a systematic…
Simulated Tempering: A New Monte Carlo Scheme
Enzo Marinari, Giorgio Parisi
We propose a new global optimization method ({\em Simulated Tempering}) for simulating effectively a system with a rough free energy landscape (i.e. many coexisting states) at fini…
On the Stability of a Stringy Black Hole
A. Carlini, F. Fucito, M. Martellini
We study the stability under perturbations of a charged four dimensional stringy black hole arising from gauging a previously studied WZW model. We find that the black hole is stab…
