Conformal geometry of the (discrete) Schwarzian Davey-Stewartson II hierarchy
B. G. Konopelchenko, W. K. Schief
The conformal geometry of the Schwarzian Davey-Stewartson II hierarchy and its discrete analogue is investigated. Connections with discrete and continuous isothermic surfaces and g…
Symmetry constraints for dispersionless integrable equations and systems of hydrodynamic type
L. V. Bogdanov, B. G. Konopelchenko
Symmetry constraints for (2+1)-dimensional dispersionless integrable equations are considered. It is demonstrated that they naturally lead to systems of hydrodynamic type which ari…
Sudakov Electroweak effects in transversely polarized beams
P. Ciafaloni, D. Comelli, A. Vergine
We study Standard Model electroweak radiative corrections for fully inclusive observables with polarized fermionic beams. Our calculations are relevant in view of the possibility f…
Direct Solution of Renormalization Group Equations of QCD in space: NLO Implementations at Leading Twist
Alessandro Cafarella, Claudio Coriano'
We illustrate the implementation of a method based on the use of recursion relations in (Bjorken) space for the solution of the evolution equations of QCD for all the leading t…
Nonlinear Beltrami equation and tau-function for dispersionless hierarchies
L. V. Bogdanov, B. G. Konopelchenko
It is proved that the action for nonlinear Beltrami equation (quasiclassical dbar-problem) evaluated on its solution gives a tau-function for dispersionless KP hierarchy. Infinites…
Neutrino Oscillations: A Global Analysis
G. L. Fogli, E. Lisi, A. Marrone +3
We review the status of the neutrino oscillation physics (as of June 2003), with a particular emphasis on the present knowledge of the neutrino mass-mixing parameters in a three ge…
Binary black holes in Mkns as sources of gravitational radiation for space based interferometers
F. De Paolis, G. Ingrosso, A. A. Nucita +1
The possibility that some Markarian objects (e.g. Mkn 501, Mkn 421 and Mkn 766) host massive binary black hole systems with eccentric orbits at their centers has been considered. T…
Pseudo-Hermitian Hamiltonians, indefinite inner product spaces and their symmetries
A. Blasi, G. Scolarici, L. Solombrino
We extend the definition of generalized parity , charge-conjugation and time-reversal operators to nondiagonalizable pseudo-Hermitian Hamiltonians, and we use these gene…
The two-dimensional Wess-Zumino model in the Hamiltonian lattice formulation
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We investigate a Hamiltonian lattice version of the two-dimensional Wess-Zumino model, with special emphasis to the pattern of supersymmetry breaking. Results are obtained by Quant…
A Semantic Approach to the Completeness Problem in Quantum Mechanics
Claudio Garola, Sandro Sozzo
The old Bohr-Einstein debate about the completeness of quantum mechanics (QM) was held on an ontological ground. The completeness problem becomes more tractable, however, if it is…
Numerical analysis of the one-mode solutions in the Fermi-Pasta-Ulam system
Alessandro Cafarella, Mario Leo, Rosario Antonio Leo
The stability of the one-mode nonlinear solutions of the Fermi-Pasta-Ulam - system is numerically investigated. No external perturbation is considered for the one-mode exact an…
Large Scale Air Shower Simulations and the Search for New Physics at AUGER
Alessandro Cafarella, Claudio Coriano, Alon E. Faraggi
Large scale airshower simulations around the GZK cutoff are performed. An extensive analysis of the behaviour of the various subcomponents of the cascade is presented. We focus our…
Level truncation and the quartic tachyon coupling
Matteo Beccaria, Carlo Rampino
We discuss the convergence of level truncation in bosonic open string field theory. As a test case we consider the calculation of the quartic tachyon coupling . We determine t…
Addendum to: Solar neutrino oscillation parameters after first KamLAND results
G. L. Fogli, E. Lisi, A. Marrone +3
In a previous paper [1], we presented a three-flavour oscillation analysis of the solar neutrino measurements and of the first data from the KamLAND experiment, in terms of the rel…
Backward electroproduction of pi0 mesons on protons in the region of nucleon resonances at four momentum transfer squared Q**2 = 1.0 GeV**2
G. Laveissiere
Exclusive electroproduction of pi0 mesons on protons in the backward hemisphere has been studied at Q**2 = 1.0 GeV**2 by detecting protons in the forward direction in coincidence w…
Novel approach to the study of quantum effects in the early universe
A. Geralico, G. Landolfi, G. Ruggeri +1
We develop a theoretical frame for the study of classical and quantum gravitational waves based on the properties of a nonlinear ordinary differential equation for a function $σ(η)…
Multiscale image analysis applied to gamma/hadron discrimination for VHE gamma-ray astronomy with ARGO-YBJ
I. De Mitri, G. Marsella, F. Salamida
Intrinsic differences in the processes involved in the development of electromagnetic and hadronic showers in the atmosphere have been evidenced by means of a careful analysis of t…
Galilean noncommutative gauge theory: symmetries & vortices
P. A. Horvathy, L. Martina, P. C. Stichel
Noncommutative Chern-Simons gauge theory coupled to nonrelativistic scalars or spinors is shown to admit the ``exotic'' two-parameter-centrally extended Galilean symmetry, realized…
String Inspired Neutrino Mass Textures in Light of KamLAND and WMAP
Claudio Coriano, Alon E. Faraggi
Recent data from astrophysical and terrestrial experiments indicates large mixing angles in the neutral lepton sector and restricts the allowed regions of neutrino masses. In parti…
Analog read-out of the RPCs in the ARGO-YBJ experiment
M. Iacovacci, S. Catalanotti, P. Creti +2
The ARGO-YBJ experiment, currently under construction at the Yangbaijing Laboratory (4300 m a.s.l.), consists of a single layer of about 2000 Resistive Plate Chambers (RPCs) for a…
The Trigger System of the ARGO-YBJ detector
S. Mastroianni, A. Aloisio, S. Catalanotti +7
The ARGO-YBJ experiment has been designed to detect air shower events over a large size scale and with an energy threshold of a few hundreds GeV. The building blocks of the ARGO-YB…
Identification of Showers with Cores Outside the ARGO-YBJ Detector
G. Di Sciascio, C. Bleve, T. Di Girolamo +2
In any EAS array, the rejection of events with shower cores outside the detector boundaries is of great importance. A large difference between the true and the reconstructed shower…
