The Effects of the Peak-Peak Correlation on the Peak Model of Hierarchical Clustering
A. Manrique, A. Raig, J. M. Solanes +3
In two previous papers a semi-analytical model was presented for the hierarchical clustering of halos via gravitational instability from peaks in a random Gaussian field of density…
Finite Lattice Hamiltonian Computations in the P-Representation: the Schwinger Model
J. M. Aroca, H. Fort, Gonzalo Alvarez-Campot
The Schwinger model is studied in a finite lattice by means of the P-representation. The vacuum energy, mass gap and chiral condensate are evaluated showing good agreement with the…
Report of the Working Group on Goldstone Boson Production and Decay
J. Bijnens, G. Colangelo, G. D'Ambrosio +11
This is the summary of the working group on Goldstone Boson Production and Decay of the Chiral Dynamics Workshop in Mainz, September 1-5, 1997. For the production aspects we discus…
Combining Multiple Methods for the Automatic Construction of Multilingual WordNets
Jordi Atserias, Salvador Climent, Xavier Farreres +2
This paper explores the automatic construction of a multilingual Lexical Knowledge Base from preexisting lexical resources. First, a set of automatic and complementary techniques f…
Nucleosynthesis in Classical Novae: ONe vs. CO White Dwarfs
Jordi Jose, Margarita Hernanz
Detailed nucleosynthesis in the ejecta of classical novae has been determined for a grid of hydrodynamic nova models. The reported 14 evolutionary sequences, followed from the onse…
Matching the Heavy Vector Meson Theory
J. Bijnens, P. Gosdzinsky, P. Talavera
We show how to obtain a ``heavy'' meson effective lagrangian for the case where the number of heavy particles is not conserved. We apply the method in a simple example at tree leve…
