Abstract
We utilize the Hamiltonian approach to the light-front formulation of quantum field theory to study two- and three-body relativistic bound-state problems in a truncated Fock-space basis in 1+1 dimensions. The problem is numerically solved by diagonalizing the invariant-mass operator in the truncated basis. We present results for binding energies, valence wave functions, and the momentum distribution functions. We discuss the advantages of the present technique over the usual integral-equation approach.
