Energy constrained sandpile models

Alessandro Chessa, Enzo Marinari, Alessandro Vespignani

We study two driven dynamical systems with conserved energy. The two automata contain the basic dynamical rules of the Bak, Tang and Wiesenfeld sandpile model. In addition a global…

Dualities Compositeness and Spacetime Structure of 4d Extreme Stringy Black Holes

M. Cadoni

We study the BPS black hole solutions of the (truncated) action for heterotic string theory compactified on a six-torus. The O(3,Z) duality symmetry of the theory, together with th…

On the Spatial Density Matrix for the Centre of Mass of a one dimensional Perfect Gas

B. Carazza

We examine the reduced density matrix of the centre of mass on position basis considering a one-dimensional system of non-interacting distinguishable particles in a infinitely…

Anomalous diffusion modifies solar neutrino fluxes

G. Kaniadakis, A. Lavagno, M. Lissia +1

Density and temperature conditions in the solar core suggest that the microscopic diffusion of electrons and ions could be nonstandard: Diffusion and friction coefficients are ener…

A Generalization of the Brodsky-Lepage Formalism

L. Houra-Yaou, P. Kessler, J. Parisi +2

We present an approach that generalizes in a natural way the perturbative QCD formalism developed by Brodsky and Lepage for the study of exclusive hadronic processes to the case of…

Off-diagonal Helicity Density Matrix Elements for Vector Mesons Produced at LEP

Mauro Anselmino, Marc Bertini, Francesco Murgia +1

Final state quark-antiquark interactions may give origin to non zero values of the off-diagonal element rho_{1,-1} of the helicity density matrix of vector mesons produced in e+e-…

Single-Spin Asymmetries in and Chiral Symmetry

Mauro Anselmino, Alessandro Drago, Francesco Murgia

We study a possible origin of single spin asymmetries in the large inclusive production of hadrons in the scattering of unpolarized protons or leptons on transversely polariz…

Kinetic model for q-deformed bosons and fermions

G. Kaniadakis, A. Lavagno, P. Quarati

We have studied the kinetics of -deformed bosons and fermions, within a semiclassical approach. This investigation is realized by introducing a generalized exclusion-inclusion p…

Magnetic properties of neutrinos in high temperature SU(2)XU(1) gauge theory

A. Erdas, C. W. Kim, T. H. Lee

We calculate the finite temperature self-energy for neutrinos in the presence of a constant magnetic field in a medium in the unbroken model. We obtain the exa…

Production of Meson Pairs Involving Mesons in Photon-Photon Collisions

L. Houra-Yaou, P. Kessler, J. Parisi +2

We present a formalism for studying the exclusive production or decay of mesons with any value of the internal orbital angular momentum L. As an application, we discuss the product…
