On perturbative quantum field theory with boundary
arXiv:hep-th/0309119 · doi:10.1016/j.nuclphysb.2004.01.018
Abstract
Boundary quantum field theory is investigated in the Lagrangian framework. Models are defined perturbatively around the Neumann boundary condition. The analyticity properties of the Green functions are analyzed: Landau equations, Cutkosky rules together with the Coleman-Norton interpretation are derived. Illustrative examples as well as argument for the equivalence with other perturbative expansions are presented.
