Recent Research Interests

In the last years my main research interest has been on non-perturbative QCD and dynamical mass generation.

Almost all the visible mass in the universe arises from dynamical mass generation, a mechanism that converts chiral current quarks into constituent quarks, each carrying one third of the proton mass. Unfortunately, perturbation theory breaks down in the IR and our knowledge of  the mechanism must rely on numerical simulations on a lattice.

Quite recently, I developed a purely analytical method for dealing with the low energy limit of Yang-Mills theory and QCD. The method is based on a change of the expansion point of ordinary perturbation theory and provides explicit and very accurate expressions for the propagators, which are the main blocks for building an analytical description of QCD from first principles. Of course, a lot of work still has to be done in that direction.

Old Interests

Since 1985, in more than thirty years, I have been working on many different topics of theoretical and mathematical physics, ranging from condensed matter and many body theory to quantum field theory and particle physics. Among them are: chemisorption and magnetic impurities, superconductivity and gauge-symmetry breaking, fullerenes, disordered systems, dense hydrogen and alkali metals, model Hamiltonians and magnetic properties, quantum phase transitions, electroweak interactions, Higgs sector, Left-Right symmetric extensions of the standard model (SM) of particle physics, non perturbative and variational methods, Renormalization Group, Gaussian effective potential, effective theories for radiative corrections, nonperturbative QCD.
