Bosonization and the lattice Gross-Neveu model
Matteo Beccaria
We consider a lattice version of the bosonized Gross-Neveu model. It is explicitely chiral symmetric and its numerical simulation does not involve any anticommuting field. We study…
Black Hole Complementarity and the Physical Origin of the Stretched Horizon
Michele Maggiore
We discuss the idea of black hole complementarity, recently suggested by Susskind et al., and the notion of stretched horizon, in the light of the generalized uncertainty principle…
The algebraic structure of the generalized uncertainty principle
Michele Maggiore
We show that a deformation of the Heisenberg algebra which depends on a dimensionful parameter is the algebraic structure which underlies the generalized uncertainty principle…
New Universality Classes for Two-Dimensional -Models
Sergio Caracciolo, Robert G. Edwards, Andrea Pelissetto +1
We argue that the two-dimensional -invariant lattice -model with mixed isovector/isotensor action has a one-parameter family of nontrivial continuum limits, only one of wh…
A General Limitation on Monte Carlo Algorithms of Metropolis Type
Sergio Caracciolo, Andrea Pelissetto, Alan D. Sokal
We prove that for any Monte Carlo algorithm of Metropolis type, the autocorrelation time of a suitable ``energy''-like observable is bounded below by a multiple of the correspondin…
The Kramers equation simulation algorithm II. An application to the Gross-Neveu model
Matteo Beccaria, Giuseppe Curci, Luca Galli
We continue the investigation on the applications of the Kramers equation to the numerical simulation of field theoretic models. In a previous paper we have described the theory an…
The Kramers equation simulation algorithm I. Operator analysis
Matteo Beccaria, Giuseppe Curci
Using an operatorial formalism, we study the Kramers equation and its applications to numerical simulations. We obtain classes of algorithms which may be made precise at every desi…
Two dimensional SU(N) x SU(N) chiral models on the lattice
Paolo Rossi, Ettore Vicari
Lattice chiral models are analyzed by strong and weak coupling expansions and by numerical simulations. order strong coupling series for the free and…
Scaling, asymptotic scaling and Symanzik improvement. Deconfinement temperature in SU(2) pure gauge theory
Giancarlo cella, Giuseppe Curci, Raffaele Tripiccione +1
We report on a high statistics simulation of SU(2) pure gauge field theory at finite temperature, using Symanzik action. We determine the critical coupling for the deconfinement ph…
Stationary Solutions and Closed Time-Like Curve in 2+1 Dimensional Gravity
P. Menotti, D. Seminara
We give the general solution of the stationary problem of 2+1 dimensional gravity in presence of extended sources, also endowed with angular momentum. We solve explicitly the compa…
The expansion of two-dimensional spin models
Massimo Campostrini, Paolo Rossi
A general two-dimensional spin model with U invariance, interpolating between $\CPN$ and models, is studied in detail in order to illustrate both the general fea…
Quantum Groups, Gravity, and the Generalized Uncertainty Principle
Michele Maggiore
We investigate the relationship between the generalized uncertainty principle in quantum gravity and the quantum deformation of the Poincaré algebra. We find that a deformed Newton…
Phenomenological Implications of Supersymmetry Breaking by the Dilaton
R. Barbieri, J. Louis, M. Moretti
We investigate the low energy properties of string vacua with spontaneously broken supersymmetry by a dilaton -term. As a consequence of the universal couplings of the dil…
Decay and Supersymmetry
R. Barbieri, G. F. Giudice
The inclusive radiative -decay is a sensitive probe of new physics, especially if related to the virtual exchange of a charged Higgs boson. Supersymmetric models provide a parti…
Physics at Hadron Colliders
A. K. Likhoded, S. R. Slabospitsky, M. Mangano +1
In this paper we summarize the results of the theory working group dedicated to the analysis of production at hadron colliders.
On the B and J/Psi Cross Section Measurements at Ua1 and CDF
Michelangelo MANGANO
We analise the implications of the measurement of and inclusive \pt\ distributions performed in collisions by the UA1 and CDF experiments.
Renormalization and topological susceptibility on the lattice: SU(2) Yang-Mills theory
Bartomeu Alles, Massimo Campostrini, Adriano Di Giacomo +2
The renormalization functions involved in the determination of the topological susceptibility in the SU(2) lattice gauge theory are extracted by direct measurements, without relyin…
Charge Screening, Large-N, and the Abelian Projection Model of Confinement
L. DelDebbio, M. Faber, J. Greensite
We point out that the abelian projection theory of quark confinement is in conflict with certain large-N predictions. According to both large-N and lattice strong-coupling argument…
Finite size scaling in CP(N-1) models
Paolo Rossi, Ettore Vicari
Finite size effects in Euclidean models with periodic boundary conditions are investigated by means of the expansion and by Monte Carlo simulations. Analytic…
A Generalized Uncertainty Principle in Quantum Gravity
Michele Maggiore
We discuss a Gedanken experiment for the measurement of the area of the apparent horizon of a black hole in quantum gravity. Using rather general and model-independent consideratio…
Lattice Perturbation Theory by Computer Algebra: A Three-Loop Result for the Topological Susceptibility
B. Alles, M. Campostrini, A. Feo +1
We present a scheme for the analytic computation of renormalization functions on the lattice, using a symbolic manipulation computer language. Our first nontrivial application is a…
