The Hierarchy Principle and the Large Mass Limit of the Linear Sigma Model
Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri
In perturbation theory we study the matching in four dimensions between the linear sigma model in the large mass limit and the renormalized nonlinear sigma model in the recently pr…
Physical Unitarity for Massive Non-abelian Gauge Theories in the Landau Gauge: Stueckelberg and Higgs
Ruggero Ferrari, Andrea Quadri
We discuss the problem of unitarity for Yang-Mills theory in the Landau gauge with a mass term a la Stueckelberg. We assume that the theory (non-renormalizable) makes sense in some…
Neutrino masses and non abelian horizontal symmetries
V. Antonelli, F. Caravaglios, R. Ferrari +1
Recent neutrino experiments have made very significant progresses and our knowledge of neutrino masses and mixing has considerably improved. In a model independent Monte Carlo appr…
The solar neutrino puzzle: present situation and future scenarios
P. Aliani, V. Antonelli, R. Ferrari +2
We present a short review of the existing evidence in favor of neutrino mass and neutrino oscillations which come from different kinds of experiments. We focus our attention in par…
Determination of Neutrino mixing parameters after SNO oscillation evidence
P. Aliani, V. Antonelli, M. Picariello +2
An updated analysis of all available neutrino oscillation evidence in Solar experiments (SK day and night spectra, global rates from Homestake, SAGE and GALLEX) including the lates…
Algebraic Aspects of the Background Field Method
R. Ferrari, M. Picariello, A. Quadri
We discuss some algebraic properties of the background field method. We introduce an extra gauge-fixing term for the background gauge field right at the beginning in the action in…
