Kähler Anomaly Effect in Anomaly Mediation Framework

Abstract

We extend the anomaly mediation mechanism by including the effect due to Kähler anomaly. We give a general method analyzing the soft breaking terms in MSSM by introducing a set of parameters. One of the parameters describes the magnitude of the Kähler contribution as opposed to the ordinary super-Weyl contribution. The other parameters come from the so-called bilinear terms which are added to the Kähler potential in order for the gauge singlet scalar masses squared to be positive. We explore allowed regions of these parameters by considering present experimental bound and present a new way of looking at model building.
