Quantum-Classical Correspondence in Energy Space: Two Interacting Spin-Particles

Fausto Borgonovi, Italo Guarneri, Felix Izrailev

The Hamiltonian conservative system of two interacting particles has been considered both in classical and quantum description. The quantum model has been realized using a symmetri…

The nucleon Drell-Hearn-Gerasimov sum rule within a relativistic constituent quark model

F. Cardarelli, B. Pasquini, S. Simula

The Drell-Hearn-Gerasimov sum rule for the nucleon is investigated within a relativistic constituent quark model formulated on the light-front. The contribution of the N - Delta(12…

Chaos and Thermalization in a Dynamical Model of Two Interacting Particles

F. Borgonovi, I. Guarneri, F. M. Izrailev +1

A quantum dynamical model of two interacting spins, with chaotic and regular components, is investigated using a finite two-particles symmetrized basis. Chaotic eigenstates give ri…

Leading asymmetries in two-hadron production in e^+e^- annihilation at the Z pole

D. Boer, R. Jakob, P. J. Mulders

We present the leading unpolarized and single spin asymmetries in inclusive two-hadron production in electron-positron annihilation at the Z pole. The azimuthal dependence in the u…

Selectivity of the 16O(e,e'pp) reaction to discrete final states

C. Giusti, F. D. Pacati, K. Allaart +3

Resolution of discrete final states in the O(e,epp)C reaction may provide an interesting tool to discriminate between contributions from one- and two-body currents…

X-ray emission from dark clusters of MACHOs

F. De Paolis, G. Ingrosso, Ph. Jetzer +1

MACHOs (Massive Astrophysical Compact Halo Objects) - as discovered by microlensing experiments towards the LMC - provide a natural explanation for the galactic halo dark matter. A…

Microlensing implications for halo dark matter

F. De Paolis, Ph. Jetzer, G. Ingrosso +1

The observations of microlensing events in the Large Magellanic Cloud suggest that a sizable fraction ( 50%) of the galactic halo is in the form of MACHOs (Massive Astrophysi…

Multi-scattering effects in (e,e'p) knockout

P. Demetriou, S. Boffi, C. Giusti +1

Multistep direct scattering of the ejectile proton is considered in (e,e'p) reactions in the quasi-free region as an improvement over the usual treatment of final-state interaction…

Charge-Exchange and multi-scattering effects in (e,e'n) knockout

P. Demetriou, S. Boffi, C. Giusti +1

Final-state interactions in (e,e'n) knockout reactions in the quasi-free region are studied by considering the multistep direct scattering of the ejectile nucleon. Primary and mult…

The N=2 Super Yang-Mills Low-Energy Effective Action at Two Loops

A. De Giovanni, M. T. Grisaru, M. Rocek +2

We have carried out a two loop computation of the low-energy effective action for the four-dimensional N=2 supersymmetric Yang-Mills system coupled to hypermultiplets, with the chi…

Six-Fermion Calculation of Intermediate-mass Higgs Boson Production at Future Colliders

G. Montagna, M. Moretti, O. Nicrosini +1

The production of an intermediate-mass Higgs boson in processes of the kind fermions at the energies of future linear colliders is studied. The recently developed a…

The Quantum Tomographic Roulette Wheel

G. M. D'Ariano, M. G. A. Paris

Random-phase homodyne tomography of the field intensity is a concrete example of the Quantum Roulette of Helstrom. In this paper we give the explicit POM of such measurement and co…

Optical von Neumann measurement

G. M. D'Ariano, M. F. Sacchi

We present an optical scheme that realizes the standard von Neumann measurement model, providing an indirect measurement of a quadrature of the field with controllable Gaussian sta…

Trace forms for the generalized Wigner functions

G. M. D'Ariano, M. F. Sacchi

We derive simple formulas connecting the generalized Wigner functions for -ordering with the density matrix, and vice-versa. These formulas proved very useful for quantum mechan…

Treatment of the current in electromagnetic two-nucleon knockout reactions

C. Giusti, F. D. Pacati, H. Arenhoevel +1

The contribution of the (1232) isobar to the electromagnetic current of the two-nucleon system and its role in (,NN) processes is investigated. The difference between the gen…

Halo dark clusters of brown dwarfs and molecular clouds

F. De Paolis, G. Ingrosso, Ph. Jetzer +1

The observations of microlensing events in the Large Magellanic Cloud suggest that a sizable fraction (\sim 50%) of the galactic halo is in the form of MACHOs (Massive Astrophysica…

Landauer and Thouless Conductance: a Band Random Matrix Approach

Giulio Casati, Italo Guarneri, Giulio Maspero

We numerically analyze the transmission through a thin disordered wire of finite length attached to perfect leads, by making use of banded random Hamiltonian matrices. We compare t…
