A class of nonlinear wave equations containing the continuous Toda case
E. Alfinito, M. S. Causo, G. Profilo +1
We consider a nonlinear field equation which can be derived from a binomial lattice as a continuous limit. This equation, containing a perturbative friction-like term and a free pa…
Effects of state dependent correlations on nucleon density and momentum distributions
F. Arias de Saavedra, G. Co', M. M. Renis
The proton momentum and density distributions of closed shell nuclei are calculated within a model treating short--range correlations up to first order in the cluster expansion. Th…
Pulsars Tracing Black Holes in Globular Clusters
F. De Paolis, V. G. Gurzadyan, G. Ingrosso
Results of precise measurements of the periods of pulsars discovered in the central regions of globular clusters are shown to be approaching the capabilities of testing the existen…
Observability at LEP2 hadronic channels of a Z' with small lepton couplings
G. Montagna, F. Piccinini, J. Layssac +2
We consider the effects of a number of models with one extra , with enhanced couplings to quarks, in the final \underline{hadronic} channels at LEP2. We show that, for a number…
Nonlinear Spectral Characterization of Discrete Data
M. Boiti, J. Leon, F. Pempinelli
The explicit analytical expression of the Nonlinear Fourier Transform (NFT) of a finite set of data is provided. Then a simple recursion relation for the NFT is constructed as a fu…
Octonionic Dirac Equation
Stefano De Leo, Khaled Abdel-Khalek
In order to obtain a consistent formulation of octonionic quantum mechanics (OQM), we introduce left-right barred operators. Such operators enable us to find the translation rules…
Octonionic Quantum Mechanics and Complex Geometry
Stefano De Leo, Khaled Abdel-Khalek
The use of complex geometry allows us to obtain a consistent formulation of octonionic quantum mechanics (OQM). In our octonionic formulation we solve the hermiticity problem and d…
Octonionic Representations of GL(8,R) and GL(4,C)
Stefano De Leo, Khaled Abdel-Khalek
Octonionic algebra being nonassociative is difficult to manipulate. We introduce left-right octonionic barred operators which enable us to reproduce the associative GL(8,R) group.…
Algebraic algorithm for the computation of one-loop Feynman diagrams in lattice QCD with Wilson fermions
Giuseppe Burgio, Sergio Caracciolo, Andrea Pelissetto
We describe an algebraic algorithm which allows to express every one-loop lattice integral with gluon or Wilson-fermion propagators in terms of a small number of basic constants wh…
Generalized integrable hierarchies and Combescure symmetry transformations
L. V. Bogdanov, B. G. Konopelchenko
Unifying hierarchies of integrable equations are discussed. They are constructed via generalized Hirota identity. It is shown that the Combescure transformations, known for a long…
Half-whole Dimensions in Quaternionic Quantum Mechanics
Stefano De Leo
We introduce {\em half-whole} dimensions for quaternionic matrices and propose a quaternionic version of the Frobenius-Schur theorem which allows us to obtain the proper quaternion…
Odd Dimensional Translation between Complex and Quaternionic Mechanics
Stefano De Leo, Pietro Rotelli
We complete the rules of translation between standard complex quantum mechanics (CQM) and quaternionic quantum mechanics (QQM) with a complex geometry. In particular we describe ho…
Quaternionic Electroweak Theory
Stefano De Leo, Pietro Rotelli
We explicitly develop a quaternionic version of the electroweak theory, based on the local gauge group . The need of a complex projection for our Lagra…
Algebraic properties of the 1+1 dimensional Heisenberg spin field model
E. Alfinito, M. Leo, R. A. Leo +2
The Estabrook-Wahlquist prolongation method is applied to the (compact and noncompact) continuous isotropic Heisenberg model in 1 + 1 dimensions. Using a special realization (an al…
The symmetry structure of the heavenly equation
E. Alfinito, G. Soliani, L. Solombrino
We show that excitations of physical interest of the heavenly equation are generated by symmetry operators which yields two reduced equations with different characteristics. One eq…
Model calculations of doubly closed shell nuclei in CBF theory III. j-j coupling and isospin dependence
F. Arias de Saavedra, G. Co', A. Fabrocini +1
Correlated Basis Function theory and Fermi Hypernetted Chain technique are extended to study medium-heavy, doubly closed shell nuclei in j-j coupling scheme, with different single…
Mean-field calculations of quasi-elastic responses in 4He
M. Anguiano, A. M. Lallena, G. Co'
We present calculations of the quasi-elastic responses functions in 4He based upon a mean-field model used to perform analogous calculations in heavier nuclei. The meson exchange c…
Chern-Simons Field Theory and Completely Integrable Systems
L. Martina, O. K. Pashaev, G. Soliani
We show that the classical non-abelian pure Chern-Simons action is related in a natural way to completely integrable systems of the Davey-Stewartson hyerarchy, via reductions of th…
Hadrophilic Z':a bridge from LEP1, SLC and CDF to LEP2 anomalies
P. Chiappetta, J. Layssac, F. M. Renard +1
In order to explain possible departures from the Standard Model predictions for and production at peak, we propose the existence of a vector boson with…
