A New Tool for the Lamb Shift Calculation
M. Cavicchi, A. Vairo
We solve the Bethe-Salpeter equation for hydrogenic bound states by choosing an appropriate interaction kernel . We want to use our solution to calculate up to a higher order…

A Bilocal Field Approach to the Large-N Expansion of Two-Dimensional (Gauge) Theories
M. Cavicchi
We consider a wide class of two-dimensional models as gauge theories, Gross-Neveu model, and -like models using a formalism based on the introduction of bilocal fi…

The Master Field of QCD and the 'T Hooft Equation
M. Cavicchi, P. Di Vecchia, I. Pesando
We rewrite the action for in the light cone gauge only in terms of a bilocal mesonic field. In this formalism the expansion can be done in a straightforward way by a…
