There is an odd tension in electroweak physics. Perturbation theory is extremely successful.
At the same time, fundamental field theory gives manifold reasons why this should not be the …

In the 2006/2007 academic year, the masters (Laurea Magistrale) courses were reorganised
to match the lines of research in the physics department of the University of Rome “La …

The Standard Model of the electroweak and strong interactions of particle physics is a
quantum field theory. Elementary particles are not indivisiblepieces' of matter but energy …

We show that it is possible to accommodate physical scalar resonances within a minimal
nonlinearly realized electroweak theory in a way compatible with a natural Hopf algebra …

The experimental evidence on the behavior of matter on subatomic scales collected so far
leads to the conclusion that all microscopic physical phenomena can be explained by the …

We propose a reformulation of electrodynamics in terms of a {\it physical} vector potential
entirely free of gauge ambiguities. Quantizing the theory leads to a propagator that is gauge …

Whenever our basic understanding of the fundamental laws of physics improves, when more
unified formalisms are uncovered, these advances are branded by subtle reformulations of …

Gauge invariance is the basis of the modern theory of electroweak and strong interactions
(the so-called standard model). A number of authors have discussed the ideas and history of …

The photon, an abstract concept belonging to a global vacuum, only manifests itself during
interaction with matter. Fundamentals of Photon Physics describes the richly faceted, basic …
