Description
The experimental signatures of supersymmetric extensions
of the Standard Model, such as the Minimal Supersymmetric
Standard Model (MSSM), depend on the actual spectrum of
superpartners, which in turn is determined by the mechanism
responsible for the breaking of supersymmetry and for its mediation
to the MSSM. An attractive possibility, known as gauge mediation,
is that supersymmetry breaking be transmitted by gauge interactions
through loops of messenger fields. In this talk, I will discuss the
possibility that the messenger fields couple to the Higgs multiplets
of an underlying Grand Unified Theory. This leads to rather unusual
supersymmetric spectra, with distinctive collider signatures and
implications for cosmology.
