Z' Reservation at LEP2
G. Montagna, O. Nicrosini, F. Piccinini +2
We consider the possibility that one extra exists with arbitrary mass and fermion couplings that do not violate (charged) lepton universality. We show that, in such a…
Nuclear Compton scattering in the -resonance region with polarized photons
B. Pasquini, S. Boffi
Nuclear Compton scattering in the -resonance region is reconsidered within the framework of the -hole model. The different role of the resonant and non-resonant contributions…
A Test of the Eikonal Approximation in High-Energy (e,e'p) Scattering
A. Bianconi, M. Radici
The Glauber method is extensively used to describe the motion of a hadronic projectile in interaction with the surrounding nuclear medium. One of the main approximations consists i…
Hyperon Polarizabilities in the Bound State Soliton Model
Carlo Gobbi, Carlos L. Schat, Norberto N. Scoccola
A detailed calculation of electric and magnetic static polarizabilities of octet hyperons is presented in the framework of the bound state soliton model. Both seagull and dispersiv…
Universal pattern in (e,e'p) at large missing momenta: quasi-deuteron or diffractive final state interactions?
A. Bianconi, S. Jeschonnek, N. N. Nikolaev +1
The intrinsic single particle momentum distributions in nuclei are supposed to show a universal behavior at large momenta, dominated by short-range correlated pairs, or quasi-deute…
Do final state interactions obscure short range correlation effects in quasielastic scattering?
A. Bianconi, S. Jeschonnek, N. N. Nikolaev +1
Are short range correlations in the ground state of the target nucleus (initial state correlations ISC)observable inexperiments on quasielastic scattering at large missi…
Two interacting particles in an effective 2-3d random potential
Fausto Borgonovi, Dima Shepelyansky
We study the effect of coherent propagation of two interacting particles in an effective 2-3-d disordered potential. Our numerical data demonstrate that in dimension , inter…
SABSPV - A Monte Carlo Integrator for Small-Angle Bhabha Scattering
M. Cacciari, G. Montagna, O. Nicrosini +1
SABSPV is a code designed to perform a theoretical evaluation of small-angle Bhabha scattering cross sections by suitably matching fixed-order perturbative calculations and structu…
Instanton Effects in Supersymmetric Yang-Mills Theories on ALE Gravitational Backgrounds
M. Bianchi, F. Fucito, G. C. Rossi +1
In this letter we report on the computation of instanton-dominated correlation functions in supersymmetric YM theories on ALE spaces. Following the approach of Kronheimer and Nakaj…
Vortex Pair Production and Decay of a 2-D Supercurrent by a Quantum Field Theory Approach
Roberto Iengo, Giancarlo Jug
We investigate the phenomenon of the decay of a supercurrent through homogeneous nucleation of vortex-antivortex pairs in a 2-D like superconductor or superfluid by means of a quan…
TOPAZ0 2.0 - A Program for Computing De-Convoluted and Realistic Observables Around the Peak
G. Montagna, O. Nicrosini, G. Passarino +1
The program {\tt TOPAZ0} is designed for computing parameters, de-convoluted and QED-dressed cross sections and forward-backward asymmetries of annihilation into fe…
Invisible Events with Radiative Photons at LEP
G. Montagna, O. Nicrosini, F. Piccinini +1
A study of the radiative neutrino counting reaction at LEP1 and LEP2 energies is presented. An approximate expression for the spectrum of the observed pho…
HYPERON RADIATIVE DECAYS IN THE BOUND STATE SOLITON MODEL
C. L. Schat, C. Gobbi, N. N. Scoccola
The radiative decays of hyperons are studied in the framework of the bound state soliton model. Detailed predictions for the total decay widths and the E2/M1 ratios corresponding t…
WWGENPV - A Monte Carlo Event Generator For Four-Fermion Production in
G. Montagna, O. Nicrosini, F. Piccinini
The Monte Carlo program {\tt WWGENPV}, designed for computing distributions and generating events for the four-fermion process , is described. It is bas…
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…
Is the galactic halo baryonic?
F. De Paolis, G. Ingrosso, Ph. Jetzer +1
Recent observations of microlensing events in the Large Magellanic Cloud suggest that a sizeable fraction of the galactic halo is in form of MACHOs with mass less than abou 0.1 M_{…
Fractal versus QuasiClassical Diffusive Transport in a class of quantum systems
Fausto Borgonovi, Italo Guarneri
We compare the properties of transmission across one-dimensional finite samples which are associated with two types of "quantum diffusion", one related to a classical chaotic dynam…
A Renormalization Group Approach to Relativistic Cosmology
Mauro Carfora, Kamilla Piotrkowska
We discuss the averaging hypothesis tacitly assumed in standard cosmology. Our approach is implemented in a "3+1" formalism and invokes the coarse graining arguments, provided and…
