چکیده

Title of dissertation: NEW MECHANISMS FOR TRANSMISSION OF SUPERSYMMETRY BREAKING Siew Phang Ng, Doctor of Philosophy, 2004 Dissertation directed by: Associate Professor Markus A. Luty, Department of Physics We considered new mechanisms for transmission of supersymmetry breaking and their phenomenological consequences. Specifically, we investigated the scalar mass corrections via five-dimensional supergravity loops and explored the possibility that supersymmetry is an accidental symmetry of Nature. We find that both these lead to phenomenologically viable scenarios. In the former, the negative slepton mass-squared masses arising from minimal anomaly mediation is cured. In the latter, which constitutes a paradigm shift, we find a more natural framework for low-energy supersymmetry than the conventional picture.

Supersymmetry Breaking and Gauge Mediation

We review recent works on supersymmetry breaking and gauge mediation. We survey our current understanding of dynamical supersymmetry breaking mechanisms and describe new model building tools using duality, meta-stability, and stringy construction. We discuss phenomenological constraints and their solutions, paying attentions to issues with gaugino masses and electroweak symmetry breaking.

Mediation of Supersymmetry Breaking via Anti-Generation Fields

In the context of the weakly coupled heterotic string, we propose a new model of mediating supersymmetry breaking. The breakdown of supersymmetry in the hidden sector is transmitted to anti-generation fields via gravitational interactions. Subsequent transmission of the breaking to the MSSM sector occurs via gauge interactions. It is shown that the mass spectra of superparticles are phenomenolo...

New Mechanisms of Gauge-Mediated Supersymmetry Breaking

We introduce new mechanisms for the communication of supersymmetry breaking via gauge interactions. These models do not require complicated dynamics to induce a nonvanishing F term for a singlet. The first class of models communicates supersymmetry breaking to the visible sector through a “mediator” field that transforms under both a messenger gauge group of the dynamical supersymmetry breaking...

New Ideas in Symmetry Breaking *

Some old and new ideas on symmetry breaking, based on the presence of extra dimensions that have been the subject of a very fast development and intensive studies during the last years, will be presented in these lectures. Special attention will be devoted to the various compactification mechanisms, including toroidal and orbifold compactifications, and to non-trivial boundary conditions or SSc...
