Two Loop Effective Kaehler Potential

TL;DR

This paper investigates the two-loop renormalization of the effective Kaehler potential in general N=1 supersymmetric theories, providing detailed calculations and insights into quantum corrections in such models.

Contribution

It presents the first detailed calculation of the two-loop effective Kaehler potential for general N=1 supersymmetric theories with arbitrary functions.

Findings

Two-loop corrections to the Kaehler potential are explicitly computed.

The results apply to non-renormalizable theories with arbitrary superpotential and gauge kinetic functions.

The methodology can be extended to other supersymmetric models.

Abstract

In this talk we study the renormalization of the effective Kaehler potential at one and two loops for general four dimensional (non--renormalizable) N=1 supersymmetric theories described by arbitrary Kaehler potential, superpotential and gauge kinetic function. We consider the Wess-Zumino model as an example.
