Exact eigenstates and {open_quotes}triviality{close_quotes} of {lambda}({var_phi}{sup {asterisk}}{var_phi}){sup 2} theory in the Feshbach-Villars formulation
- Department of Physics and Astronomy, York University, North York, Ontario, M3J 1P3 (CANADA)
The complex scalar (Klein-Gordon) quantum field theory (QFT) with a {lambda}({var_phi}{sup {asterisk}}{var_phi}){sup 2} interaction is considered in the Feshbach-Villars formulation. It is shown that exact few-particle eigenstates of the QFT Hamiltonian can be obtained. The resulting relativistic few-body equations correspond to Klein-Gordon particles interacting via delta-function, or {open_quotes}contact,{close_quotes} potentials. Momentum-space solutions of the two-body equation yield a {open_quotes}trivial{close_quotes} unity S matrix. {copyright} {ital 1997} {ital The American Physical Society}
