HighEnergy Behavior of Feynman Amplitudes
Abstract
A method is developed for obtaining the asymptotic form of the Feynman integral associated with a general convergent nth order planar graph with two, three, or four external lines. Only graphs corresponding to the λφ^{3} theory are considered explicitly. The Feynman integrals are shown to behave asymptotically like s^{ρ}(lns)^{α}, where s is the large kinematical variable and ρ and α are integers which can be read off from the topology of the graph according to a simple rule.
