Description
In quantum field theory, clothed particles are obtained by dressing bare particles using interactions. In the clothed particle representation, there are self-energy and cloud effects that lead to mass renormalization and vertex terms. The clothing procedure allows one to express the original Hamiltonian that depends on a set of bare creation/destruction operators in a new functional form that depends on a set of clothed-particle operators, and the procedure allows one to remove divergent terms directly from the Hamiltonian in a purely algebraic manner. The key idea behind this transformation from a bare particle representation to a clothed particle representation is to obtain a representation where the physical vacuum state and one-clothed-particle states are both eigenvectors of the total Hamiltonian. During the poster session, I will present work showing how the clothing procedure can be performed using a phi^3 interaction on the light-front. I will focus on how the clothing procedure can be used to obtain a two-body interaction by carrying out the procedure to second order, and I will also discuss how the light-front vacuum is affected by the final result.
