Quantum interference effects in () reactions
A. Bianconi, S. Boffi
The response to longitudinally polarized electrons in coincident out-of-plane () reaction is discussed to study the role of final state int…
Entropy of random coverings and 4D quantum gravity
C. Bartocci, U. Bruzzo, M. Carfora +1
We discuss the counting of minimal geodesic ball coverings of -dimensional riemannian manifolds of bounded geometry, fixed Euler characteristic and Reidemeister torsion in a giv…
Semi-analytical and Monte Carlo results for the production of four fermions in collisions
G. Montagna, O. Nicrosini, G. Passarino +1
In view of the forthcoming experiments at high energy colliders, LEP2 and beyond, the process has been investigated for {\it off-shell} 's…
The apparent Coulomb reacceleration of neutrons in electrodissociation of the deuteron
A. Bianconi, S. Jeschonnek, N. N. Nikolaev +1
We demonstrate that the final state - interaction in the reaction of electrodissociation of the deuteron at large in a static external field leads to the apparent rea…
A case for a baryonic dark halo
F. De Paolis, G. Ingrosso, Ph. Jetzer +1
Recent observations of microlensing events in the Large Magellanic Cloud by the MACHO and EROS collaborations suggest that an important fraction of the galactic halo is in the form…
Light mesons production at the Tevatron to next-to-leading order
Mario Greco, Simona Rolli
Inclusive production of light mesons (, , , ) at the Tevatron is considered in QCD to next-to-leading order in the formalism of fragmentation functions.…
Final state interaction effects in scattering
A. Bianconi, S. Jeschonnek, N. N. Nikolaev +1
We present a systematic study of the final-state interaction (FSI) effects in scattering in the CEBAF energy range with particular emphasis on the phenomenon of the angu…
ALE Instantons in String Effective Theory
M. Bianchi, F. Fucito, M. Martellini +1
We show that the classical equations of motion of the low-energy effective field theory describing the massless modes of the heterotic (or type I) string admit two classes of super…
Many-body effects in 16O(e,e'p)
M. Radici, S. Boffi, Steven C. Pieper +1
Effects of nucleon-nucleon correlations on exclusive reactions on closed-shell nuclei leading to single-hole states are studied using ( MeV, $…
Simple classification of final state interaction effects in scattering
A. Bianconi, S. Jeschonnek, N. N. Nikolaev +1
The radius of interaction between the struck proton and spectator nucleons is close to the radius of short-distance two-nucleon correlations in nuclear matter, which makes final st…
Three-dimensional BF Theories and the Alexander-Conway Invariant of Knots
A. S. Cattaneo, P. Cotta-Ramusino, M. Martellini
We study 3-dimensional BF theories and define observables related to knots and links. The quantum expectation values of these observables give the coefficients of the Alexander-Con…
The Geometry of classical change of signature
M. Carfora, G. F. R. Ellis
The proposal of the possibility of change of signature in quantum cosmology has led to the study of this phenomenon in classical general relativity theory, where there has been som…
The Top Quark and the Higgs Boson Mass from LEP SLC and CDF Data
Guido Montagna, Oreste Nicrosini, Giampiero Passarino +1
The impact of the new experimental data from LEP, SLC and CDF on the top quark mass and the Higgs boson mass is investigated. The determinations of m_{top} and of an upper bound on…
J/psi Production via Fragmentation at the Tevatron
M. Cacciari, M. Greco
The production of $\jpsi$ at large transverse momenta ($\pt > M_\jpsi$) in collisions is considered by including the mechanism of fragmentation. Both contributions of fra…
Cumulant to Factorial Moment Ratio and Multiplicity Data
I. M. Dremin, V. Arena, G. Boca +8
The ratio of cumulant to factorial moments of experimental multiplicity distributions has been calculated for and interactions in a wide range of energies. As a f…
Three-Dimensional Integrable Models and Associated Tangle Invariants
B. L. Cerchiai, M. Martellini, F. Valz-Gris
In this paper we show that the Boltzmann weights of the three-dimensional Baxter-Bazhanov model give representations of the braid group, if some suitable spectral limits are taken.…
Inclusive particle photoproduction to next-to-leading order
M. Greco, S. Rolli, A. Vicini
We study the inclusive photoproduction of neutral and charged pions and at HERA, via the resolved photon mechanism, in QCD to next-to-leading order. We present various distribu…
Moduli Spaces of Curves with Homology Chains and c=1 Matrix Models
A. S. Cattaneo, A. Gamba, M. Martellini
We show that introducing a periodic time coordinate in the models of Penner-Kontsevich type generalizes the corresponding constructions to the case of the moduli space ${\cal S}_{g…
