Quantum states of elementary three-geometry
G. Carbone, M. Carfora, A. Marzuoli
We introduce a quantum volume operator in three--dimensional Quantum Gravity by taking into account a symmetrical coupling scheme of three SU(2) angular momenta. The spectrum o…
Relativistic calculation of nuclear transparency in (e,e'p) reactions
Andrea Meucci
Nuclear transparency in (e,e'p) reactions is evaluated in a fully relativistic distorted wave impulse approximation model. The relativistic mean field theory is used for the bound…
A Study of Strange Particle Production in Muon Neutrino Charged Current Interactions in the NOMAD Experiment
the NOMAD Collaboration
A study of strange particle production in muon neutrino charged current interactions has been performed using the data from the NOMAD experiment. Yields of neutral strange particle…
Microlensing search towards M31
S. Calchi Novati, G. Iovane, A. A. Marino +26
We present the first results of the analysis of data collected during the 1998-99 observational campaign at the 1.3 meter McGraw-Hill Telescope, towards the Andromeda galaxy (M31),…
Very low-frequency excitations in frustrated two-dimensional Heisenberg antiferromagnets
P. Carretta, R. Melzi, N. Papinutto +1
muSR and 7Li NMR relaxation measurements in frustrated two-dimensional S=1/2 Heisenberg antiferromagnets on a square lattice are presented. It is found that both in Li2VOSiO4 and L…
Accessing transversity with interference fragmentation functions
M. Radici, R. Jakob, A. Bianconi
We discuss in detail the option to access the transversity distribution function by utilizing the analyzing power of interference fragmentation functions in two-pion produ…
Improving quantum interferometry by using entanglement (to take a decision you'd better use entanglement)
G. M. D'Ariano, Matteo G. A Paris, Paolo Perinotti
We address the use of entanglement to improve the precision of generalized quantum interferometry, i.e. of binary measurements aimed to determine whether or not a perturbation has…
Optimal cloning for two pairs of orthogonal states
Dagmar Bruss, Chiara Macchiavello
We study the optimal cloning transformation for two pairs of orthogonal states of two-dimensional quantum systems, and derive the corresponding optimal fidelities.
Magnetic Resonance Force Microscopy Measurement of Entangled Spin States
G. P. Berman, F. Borgonovi, G. Chapline +2
We simulate magnetic resonance force microscopy measurements of an entangled spin state. One of the entangled spins drives the resonant cantilever vibrations, while the other remot…
A quantum measurement of the spin direction
G. M. D'Ariano, P. Lo Presti, M. F. Sacchi
We give a first physical model for the quantum measurement of the spin direction. It is an Arthurs-Kelly model that involves a kind of magnetic-dipole interaction of the spin with…
Measurements of extremely low radioactivity levels in BOREXINO
Borexino Collaboration, C. Arpesella
The techniques researched, developed and applied towards the measurement of radioisotope concentrations at ultra-low levels in the real-time solar neutrino experiment BOREXINO at G…
Fractal fluctuations in quantum integrable scattering
Italo Guarneri, Marcello Terraneo
We theoretically and numerically demonstrate that completely integrable scattering processes may exhibit fractal transmission fluctuations, due to typical spectral properties of in…
Search for CP Violation in the decays D+ -> K_S pi+ and D+ -> K_S K+
The FOCUS Collaboration
A high statistics sample of photo-produced charm from the FOCUS(E831) experiment at Fermilab has been used to search for direct CP violation in the decays D+->K_S pi+ and D+ -> K_S…
Using entanglement improves precision of quantum measurements
G. Mauro D'Ariano, Paoloplacido Lo Presti, Matteo G. A. Paris
We show how entanglement can be used to improve the estimation of an unknown transformation. Using entanglement is always of benefit, in improving either the precision or the stabi…

S. Boffi, L. Ya. Glozman, W. Klink +3
Results for the proton and neutron electric and magnetic form factors as well asthe nucleon axial and induced pseudoscalar form factors are presented for the chiral constituent qua…
A Rule for the Equilibrium of Forces in the Hermitian Theory of Relativity
S. Antoci
When the behaviour of the singularities, which are used to represent masses, charges or currents in exact solutions to the field equations of the Hermitian theory of relativity, is…
Quantum Measurement of a Single Spin using Magnetic Resonance Force Microscopy
G. P. Berman, F. Borgonovi, G. Chapline +5
Single-spin detection is one of the important challenges facing the development of several new technologies, e.g. single-spin transistors and solid-state quantum computation. Magne…

The FOCUS Collaboration
We describe the algorithm used to identify charged tracks in the fixed-target charm-photoproduction experiment FOCUS.
The Origin of the Electromagnetic Interaction in Einstein's Unified Field Theory with Sources
S. Antoci
Einstein's unified field theory is extended by the addition of matter terms in the form of a symmetric energy tensor and of two conserved currents. From the field equations and fro…
