Frame Dependence of the Pair Contribution to the Pion Electromagnetic Form Factor in a Light-Front Approach
J. P. B. C. de Melo, T. Frederico, E. Pace +1
The frame dependence of the pair-term contribution to the electromagnetic form factor of the pion is studied within the Light Front approach. A symmetric ansatz for the pion Bethe-…
The Cosmic-Ray Proton and Helium Spectra measured with the CAPRICE98 balloon experiment
M. Boezio, V. Bonvicini, P. Schiavon +36
A new measurement of the primary cosmic-ray proton and helium fluxes from 3 to 350 GeV was carried out by the balloon-borne CAPRICE experiment in 1998. This experimental setup comb…
On the geometry of higher-spin gauge fields
D. Francia, A. Sagnotti
We review a recent construction of the free field equations for totally symmetric tensors and tensor-spinors that exhibits the corresponding linearized geometry. These equations ar…
Classical gauge instantons from open strings
M. Billo, M. Frau, F. Fucito +3
We study the D3/D(-1) brane system and show how to compute instanton corrections to correlation functions of gauge theories in four dimensions using open string techniques. In part…
Antimatter research in Space
Piergiorgio Picozza, Aldo Morselli
Two of the most compelling issues facing astrophysics and cosmology today are to understand the nature of the dark matter that pervades the universe and to understand the apparent…
Intermittency in Turbulence: Multiplicative random process in space and time
Roberto Benzi, Luca Biferale, Federico Toschi
We present a simple stochastic algorithm for generating multiplicative processes with multiscaling both in space and in time. With this algorithm we are able to reproduce a synthet…
Multi-Instanton Calculus and Equivariant Cohomology
Ugo Bruzzo, Francesco Fucito, Jose F. Morales +1
We present a systematic derivation of multi-instanton amplitudes in terms of ADHM equivariant cohomology. The results rely on a supersymmetric formulation of the localization formu…
Search for Dark Matter with GLAST
Aldo Morselli, Andrea Lionetto, Alessandro Cesarini +2
The detection of exotic cosmic rays due to pair annihilation of dark matter particles in the Milky Way halo is a viable techniques to search for supersymmetric dark matter candidat…
Study of the coincidences between the gravitational wave detectors EXPLORER and NAUTILUS in 2001
P. Astone, D. Babusci, M. Bassan +23
We report the result from a search for bursts of gravitational waves using data collected by the cryogenic resonant detectors EXPLORER and NAUTILUS during the year 2001, for a tota…
Preliminary results of an aging test of RPC chambers for the LHCb Muon System
Andrea Bizzeti, Giovanni Carboni, Gianmaria Collazuol +7
The preliminary results of an aging test performed at the CERN Gamma Irradiation Facility on a single--gap RPC prototype developed for the LHCb Muon System are presented. The resul…
The lattice scale at large beta in quenched QCD
M. Guagnelli, R. Petronzio, N. Tantalo
In this paper we extend the estimate of the value of the lattice spacing a in units of the r0 scale at values of the bare coupling larger than those available. By using results fro…
PWIA Extraction of the Neutron Magnetic Form Factor from Quasi-Elastic 3He(e,e') at Q^2 = 0.3 to 0.6 (GeV/c)^2
W. Xu
A high precision measurement of the transverse spin-dependent asymmetry A_{T'} in ^3 vec{He}(vec{e},e') quasielastic scattering was performed in Hall A at Jefferson Lab at values o…
Free geometric equations for higher spins
D. Francia, A. Sagnotti
We show how allowing non-local terms in the field equations of symmetric tensors uncovers a neat geometry that naturally generalizes the Maxwell and Einstein cases. The end results…

The Sigma beam asymmetry for positive pion photoproduction on the proton has been measured over an angular range of 40-170 deg at photon energies from 0.8 to 1.5 GeV. The resulting…
Testing for non-Gaussianity of the cosmic microwave background in harmonic space: an empirical process approach
Frode K. Hansen, Domenico Marinucci, Paolo Natoli +1
We present a new, model-independent approach for measuring non-Gaussianity of the Cosmic Microwave Background (CMB) anisotropy pattern. Our approach is based on the empirical distr…
