Classical Versus Quantum Symmetries for Toda Theories with a Nontrivial Boundary Perturbation
S. Penati, A. Refolli, D. Zanon
In this paper we present a detailed study of the quantum conservation laws for Toda field theories defined on the half plane in the presence of a boundary perturbation. We show tha…
On the Phenomenology of Tachyon Radiation
Ron Folman, Erasmo Recami
We present a brief overview of the different kinds of electromagnetic radiations expected to come from (or to be induced by) space-like sources (tachyons). New domains of radiation…
Field Theory of the Electron, Spin and Zitterbewegung
Erasmo Recami, Giovanni Salesi
In previous papers, we have investigated the classical theory of Barut and Zanghi (BZ) for the electron spin [which interpreted the Zitterbewegung (zbw) motion as an internal motio…
Renormalization of Matter Field Theories on the Lattice and the Flow Equation
M. Pernici, M. Raciti, F. Riva
We give a new proof of the renormalizability of a class of matter field theories on a space-time lattice; in particular we consider and massive Yukawa theories with Wilson fe…
A local and integrable lattice regularization of the massive Thirring model
C. Destri, T. Segalini
The light--cone lattice approach to the massive Thirring model is reformulated using a local and integrable lattice Hamiltonian written in terms of discrete fermi fields. Several s…
A Search for Non-Perturbative Dualities of Local Yang--Mills Theories from Calabi--Yau Threefolds
A. Ceresole, M. Billo', R. D'Auria +5
The generalisation of the rigid special geometry of the vector multiplet quantum moduli space to the case of supergravity is discussed through the notion of a dynamical Calabi--Yau…
Topological BF Theories in 3 and 4 Dimensions
Aberto S. Cattaneo, Paolo Cotta-Ramusino, Juerg Froehlich +1
In this paper we discuss topological BF theories in 3 and 4 dimensions. Observables are associated to ordinary knots and links (in 3 dimensions) and to 2-knots (in 4 dimensions). T…
R-Symmetry and the Topological Twist of N=2 Effective Supergravities of Heterotic Strings
M. Billo', R. D'Auria, S. Ferrara +3
We discuss R-symmetries in locally supersymmetric N=2 gauge theories coupled to hypermultiplets which can be thought of as effective theories of heterotic superstring models. In th…
Quantum gravity, the Planck lattice and the Standard Model
Giuliano Preparata, She-Sheng Xue
A possible ground state of Quantum Gravity is Wheeler's ``space-time foam'', which can be modeled as a ``Planck-lattice'', a space-time cubic lattice of lattice constant $a_P\simeq…
A numerical study of the RG equation for the deformed nonlinear sigma model
L. Belardinelli, C. Destri, E. Onofri
The Renormalization Group equation describing the evolution of the metric of the nonlinear sigma model poses some nice mathematical problems involving functional analysis, differen…
RENORMALONS FROM EIGHT LOOP EXPANSION OF THE GLUON CONDENSATE IN LATTICE GAUGE THEORY,
F. Di Renzo, G. Marchesini, E. Onofri
We use a numerical method to obtain the weak coupling perturbative coefficients of local operators with lattice regularization. Such a method allows us to extend the perturbative e…
Supergravity dressing of beta-functions in N=1 and N=2 supersymmetric models
M. T. Grisaru, D. Zanon
We discuss the dressing of one-loop sigma-model beta-functions by induced supergravity, for both N=1 and N=2 supersymmetric theories. We obtain exact results by a superconformal ga…
The Donaldson-Witten Invariants in Pure QCD with Order and Disorder 't Hooft-like Operators
A. S. Cattaneo, P. Cotta-Ramusino, A. Gamba +1
We study the first-order formalism of pure four-dimensional Yang--Mills theory with theta-term. We describe the Green functions associated to electric and magnetic fl…
Lagrangian description of N=2 minimal models as critical points of Landau-Ginzburg theories.
M. T. Grisaru, D. Zanon
We discuss a two-dimensional lagrangian model with supersymmetry described by a Kähler potential and superpotential which explicitly exhibits renormaliz…
Quantum integrability in two-dimensional systems with boundary
S. Penati, D. Zanon
In this paper we consider affine Toda systems defined on the half-plane and study the issue of integrability, i.e. the construction of higher-spin conserved currents in the presenc…
