On the QED Radiator at Order $α^{3}$

G. Montagna, O. Nicrosini, F. Piccinini

The $O (α^{3})$ leading logarithmic contribution to the QED radiator in the additive form is considered. The effect of the correction on two-fermion physics at LEP1 and LEP2 i…

Diffusion and localization in chaotic billiards

Fausto Borgonovi, Giulio Casati, Baowen Li

We study analytically and numerically the classical diffusive process which takes place in a chaotic billiard. This allows to estimate the conditions under which the statistical pr…

Photocouplings of nucleon resonances with gluon and pion exchange currents

E. Perazzi, M. Radici, S. Boffi

Photocouplings for the nucleon resonances most relevant to total photoabsorption are calculated in a constituent quark model including gluon and pion exchange. The sensitivity of t…

Photon electroproduction off nuclei in the $Δ$ -resonance region

B. Pasquini

The cross section for the $A (e, e^{'} γ) A$ reaction is calculated, investigating the contribution from the nuclear target with respect to the radiative corrections from the electron. Th…

WWGENPV 2.0 - A Monte Carlo Event Generator for Four-Fermion Production at e+ e- Colliders

D. G. Charlton, G. Montagna, O. Nicrosini +1

The Monte Carlo program {\tt WWGENPV}, designed for computing distributions and generating events for four-fermion production in $e^{+} e^{-}$ collisions, is described. The new versio…

Edge Tunneling of Vortices in Superconducting Thin Films

Roberto Iengo, Giancarlo Jug

We investigate the phenomenon of the decay of a supercurrent due to the zero-temperature quantum tunneling of vortices from the edge in a thin superconducting film in the absence o…

Fragmentation Functions approach in pQCD fragmentation phenomena

Simona Rolli

Next-to-leading order parton fragmentation functions into light mesons are presented. They have been extracted from real and simulated $e^{+} e^{-}$ data and used to predict inclusive s…

Critical behavior of weakly-disordered anisotropic systems in two dimensions

Giancarlo Jug, Boris N. Shalaev

The critical behavior of two-dimensional (2D) anisotropic systems with weak quenched disorder described by the so-called generalized Ashkin-Teller model (GATM) is studied. In the c…

Microscopic Oscillations in the Quantum Nucleation of Vortices Subject to Periodic Pinning Potential in a Thin Superconductor

Roberto Iengo, Giancarlo Jug

We present a theory for the decay of a supercurrent through nucleation of vortex-antivortex pairs in a two-dimensional superconductor in the presence of dissipation and of a period…

$O (α^{2})$ Next-to-Leading Photonic Corrections to Small-Angle Bhabha Scattering in the Structure Function Formalism

G. Montagna, O. Nicrosini, F. Piccinini

A general method for computing $O (α^{2})$ and higher-order next-to-leading photonic corrections is presented and applied to the precision calculation of the small-angle Bhabh…

The present theoretical error on the Bhabha scattering cross section in the luminometry region at LEP

A. Arbuzov, M. Bigi, H. Burkhardt +19

The results concerning the theoretical evaluation of the small-angle Bhabha Scattering cross section obtained during the Workshop on Physics at LEP2 (CERN, Geneva, Switzerland, 199…

Virtual Compton scattering off nuclei in the $Δ$ -resonance region

B. Pasquini, S. Boffi

Virtual Compton scattering in the $Δ$ -resonance region is considered in the case of a target nucleus. The discussion involves generalized polarizabilities and is developed for zero…

The BF Formalism for QCD and Quark Confinement

F. Fucito, M. Martellini, M. Zeni

Using the BF version of pure Yang-Mills, it is possible to find a covariant representation of the 't Hooft magnetic flux operator. In this framework, 't Hooft's pioneering work on…
