| Title: | Extra dimensions and dark matter |

| Abstract: | In this thesis we analyze the consequences of extra spacetime dimensions
on the MSSM. We begin by reviewing the MSSM in four dimensions. We
specify the superpotential and all the possible soft terms to break supersymmetry.
After describing gravity-mediated susy breaking models, we present
the mass spectrum of the MSSM. In particular we introduce the neutralinos
as lightest supersymmetric particles. They are suitable candidates for
dark matter. We present a pedagogical introduction to the method of the
effective potential. We apply this method to the MSSM in order to obtain
its renormalization group equations. We also do an analysis in terms of
Feynman diagrams. We present the string-inspired model by Dienes, Dudas
and Gherghetta [Nuclear Physics B537, 47 (1999)]. We treat different scenarios
showing how extra dimensions give rise to `power-law' running of the
parameters. We also analyze the possible implications of extra dimensions
related to the dark matter problem. Extra... |
