The inhomogeneous Bethe-Salpeter Equation for an interacting system, composed by two massive scalars exchanging a massive scalar, is numerically investigated in ladder approximation, directly in Minkowski space, by using an approach based on the Nakanishi integral representation. In this contribution, the results obtained for the scattering lengths and phase-shifts will be presented and...

In the framework of the Light-Front Tamm-Dancoff method, we applied the sector-dependent renormalization scheme to the quenched Yukawa model. A review of the results obtained in this way is given.
The Yukawa model incorporated spin is studied in the truncation N=3 (one fermion and two mesons), whereas the spinless Yukawa model is truncated up to a higher value N=4. The eigenvector...

We use algebraic methods to reconcile the triviality of the vacuum in
different light-front field theories with the inequivalence of vacuua
in different canonical theories. We show how the inequivalence arises by extending the vacuum functional from the light-font Fock algebra to
the algebra of local observables. This extension leads to an
identification of a sub-algebra of the...
