Renormalization of two - loop diagrams in scalar lattice field theory
We present a method to calculate to very high precision the coefficients of the divergences occuring in two-loop diagrams for a massive scalar field on the lattice. The approach is based on coordinate space techniques and extensive use of the precisely known Green’s function.

متن کاملAnatomy of One - Loop Effective Action in Noncommutative Scalar Field Theories 1
One-loop effective action of noncommutative scalar field theory with cubic self-interaction is studied. Utilizing worldline formulation, both planar and nonplanar parts of the effective action are computed explicitly. We find complete agreement of the result with Seiberg-Witten limit of string worldsheet computation and standard Feynman diagrammatics. We prove that, at lowenergy and large nonco...
متن کاملOne-loop Effective Potential for Scalar and Vector Fields on Higher Dimensional Noncommutative Flat Manifolds
The effective potentials for massless scalar and vector quantum field theories on D dimensional manifold with p compact noncommutative extra dimensions are evaluated by means of dimensional regularization implemented by zeta function tecniques. It is found that, the zeta function associated with the one loop operator may not be regular at the origin. Thus, the related heat kernel trace has a lo...
متن کاملTwo - loop effective potential in quantum field theory in curved space - time
Two-loop effective potential in quantum field theory in curved space-time. ABSTRACT 1) temporal postal address; The method of the calculation of effective potential (in linear curvature approximation and at any loop) in massless gauge theory in curved space-time by the direct solution of renormalization group equation is given. The closed expression for two-loop effective potential is obtained....
