The gaussian propagator formalism and the determination of the leading Regge trajectory for phi^3 field theory
Richard Hong Tuan
As the number of loops goes to infinity Feynman -parameters undergo a fixing mechanism which entails a gaussian representation for propagators in scalar field theories. Here, we…

Factorization of Spanning Trees on Feynman Graphs
R. Hong Tuan
In order to use the Gaussian representation for propagators in Feynman amplitudes, a representation which is useful to relate string theory and field theory, one has to prove first…
