Renormalization and running in the 2D $CP(1)$ model [PDF]

We calculate the scattering amplitude in the two dimensional $CP(1)$ model in a regularization scheme independent way. When using cutoff regularization, a new Feynman rule from the path integral measure is required if one is to preserve the symmetry. The

Renormalization for one-loop diagrams in gauge theory.

, 2013
In most situations, calculations of Feynman diagrams which contain loops lead to infinities. Renormalization has been known to be a standard process to circumvent this difficulty. In this project, we studied two different regularization schemes, which are

Three-loop renormalization of the quantum action for a five-dimensional scalar cubic model with the usage of the background field method and a cutoff regularization

The paper studies the quantum action for the five-dimensional real $ϕ^3$-theory in the case of a general formulation using the background field method.
