Search for non-Poissonian behavior in nuclear beta-decay

Giorgio Concas, Marcello Lissia

We performed two independent counting experiments on a beta-emitting source of Sm151 by measuring the gamma-photon emitted in a fraction of the decays. For counting times ranging f…

Trace anomaly and Hawking effect in 2D dilaton gravity theories

Mariano Cadoni

We investigate the classical and semiclassical features of generic 2D, matter-coupled, dilaton gravity theories. In particular, we show that the mass, the temperature and the flux…

Production of meson pairs, involving tensor and pseudotensor mesons, in photon-photon collisions

L. Houra-Yaou, P. Kessler, J. Parisi +2

Starting from a bound-state model of weakly bound quarks for () mesons, we derive a formalism for computing the production or decay of such mesons, whatever the value of…

Conformal equivalence of 2D dilaton gravity models

Mariano Cadoni

We investigate the behavior of generic, matter-coupled, 2D dilaton gravity theories under dilaton-dependent Weyl rescalings of the metric. We show that physical observables associa…

Spin Measurements in lp -> hX Deep Inelastic Scattering

M. Anselmino, M. Boglione, J. Hansson +1

The production of hadrons in polarized lepton-nucleon deep inelastic scattering is discussed. The helicity density matrix of the hadron is computed within the QCD hard scattering f…

Single Spin Asymmetries in Inclusive Hadron Production

M. Anselmino, M. Boglione, F. Murgia

We consider a general formalism, previously developed to describe single spin asymmetries (SSA) in inclusive particle production at moderately large in hadron-hadron high-ene…

Single spin asymmetries in DIS

M. Anselmino, E. Leader, F. Murgia

We consider possible mechanisms for single spin asymmetries in inclusive Deep Inelastic Scattering (DIS) processes with unpolarized leptons and transversely polarized nucleons. Tes…

The 2D analogue of the Reissner-Nordstrom solution

S. Monni, M. Cadoni

A two-dimensional (2D) dilaton gravity model, whose static solutions have the same features of the Reissner-Nordstrom solutions, is obtained from the dimensional reduction of a fou…

Inclusive production of hadrons in and spin measurements

M. Anselmino, M. Boglione, J. Hansson +1

We discuss the production of polarized hadrons in polarized lepton nucleon interactions and show that the helicity density matrix of the hadron, when measurable, can give informati…

Solar neutrinos: beyond standard solar models

V. Castellani, S. Degl'Innocenti, G. Fiorentini +2

After a short survey of the physics of solar neutrinos, giving an overview of hydrogen burning reactions, predictions of standard solar models and results of solar neutrino experim…

The dualities of 3D dilaton gravity

Mariano Cadoni

We investigate Brans-Dicke dilaton gravity theories in 2+1 dimensions. We show that the reduced field equations for solutions with diagonal metric and depending only on one spaceti…

Single Spin Asymmetries in Inclusive Hadron Production

Mauro Anselmino, M. Elena Boglione, Francesco Murgia

The general formalism to describe single spin asymmetries in hadron-hadron high energy and large inclusive production within the QCD-improved parton model and assuming the fa…

Photofission and Quasi-Deuteron-Nuclear State as Mixing of Bosons and Fermions

G. Kaniadakis, A. Lavagno, P. Quarati

The empirical-phenomenological quasi-deuteron photofission description is theoretically justified within the semiclassical, intermediate statistics model. The transmutational fermi…

Generalized Statistics and Solar Neutrinos

G. Kaniadakis, A. Lavagno, P. Quarati

The generalized Tsallis statistics produces a distribution function appropriate to describe the interior solar plasma, thought as a stellar polytrope, showing a tail depleted respe…

Generalized Fractional Statistics

G. Kaniadakis, A. Lavagno, P. Quarati

We link, by means of a semiclassical approach, the fractional statistics of particles obeying the Haldane exclusion principle to the Tsallis statistics and derive a generalized qua…

Physics potentials of pp and pep solar neutrino fluxes

E. Calabresu, G. Fiorentini, M. Lissia

Experimental determinations of the pp and pep fluxes have great potentialities. We briefly review the reasons that make such measurements privileged tests of neutrino properties. W…

Considerations on Localization of Macroscopic Bodies

B. Carazza, Diparimento di Fisica, Parma

Position holds a very special role in understanding the classical behaviour of macroscopic bodies on the basis of quantum principles. This lead us to examine the localised states o…

Stimulated by the experimental observation, made by the E760 Collaboration at Fermilab, of the state of charmonium resonantly formed in annihilation, we perfo…
