Gaugino masses from gravitino at one loop    [PDF]

Jae Yong Lee

The N=1 supergravity coupled to chiral and Yang-Mills superfields is regarded as the ultraviolet theory of the MSSM. The gravitino acquires a mass from the hidden sector and in turn participate in mediating supersymmetry breaking to the MSSM sector. We take into account the quantum effects of gravitino and then evaluate the gravitino contributions to the gaugino masses at one loop level, which is universal irrespective of the kinds of the SM gauge symmetries.
