Quasirenormalizable Quantum Field Theories

Polyakov, M. V. ; Semenov-Tian-Shansky, K. M. ; Smirnov, A. O. ; Vladimirov, A. A.


Leading logarithms in massless nonrenormalizable effective field theories can be computed using nonlinear recurrence relations. These recurrence relations follow from the fundamental requirements of unitarity, analyticity, and crossing symmetry of scattering amplitudes and generalize the renormalization group technique to the case of nonrenormalizable effective field theories. We review the ...
