QCD, the Parton Model, and the Nucleon Polarised Structure Functions}
Paolo M. Gensini
The present talk summarises the 1993 situation in understanding the spin structure of the nucleon via electron and muon polarised deep--inelastic scattering (PDIS). The central que…
Inclusive Quasielastic and Deep Inelastic Scattering of Polarized Electrons by Polarized He}
C. Ciofi degli Atti, S. Scopetta, E. Pace +1
A comprehensive treatement of the theoretical approach for describing nuclear effects in inclusive scattering of polarized electrons by polarized He is presented.
SU(3)--Breaking Effects in Axial--Vector Couplings of Octet Baryons
Paolo M. Gensini, Galileo Violini
Present evidence on baryon axial--vector couplings is reviewed, the main emphasis being on internal consistency between asymmetry and rate data. A complete account of all {\sl smal…
Topological Excitations in Compact Maxwell-Chern-Simons Theory
M. C. Diamantini, P. Sodano, C. A. Trugenberger
We construct a lattice model of compact (2+1)-dimensional Maxwell-Chern- Simons theory, starting from its formulation in terms of gauge invariant quantities proposed by Deser and J…
Solitary Waves and Compactons in a class of Generalized Korteweg-DeVries Equations
Fred Cooper, Harvey Shepard, Pasquale Sodano
We study the class of generalized Korteweg-DeVries equations derivable from the Lagrangian: $ L(l,p) = \int \left( \frac{1}{2} \vp_{x} \vp_{t} - { {(\vp_{x})^{l}} \over {l(l-1)}} +…
Canonical Analysis of Poincare' Gauge Theories for Two Dimansional Gravity
G. Grignani, G. Nardelli
Following the general method discussed in Refs.[1,2], Liouville gravity and the 2 dimensional model of non-Einstenian gravity can…
