. .UNIVERSITAT BONNPhysikalisches InstitutTowards Low Energy Physics from the Heterotic StringvonSaul Noe Ramos S anchezWe investigate orbifold compacti cations of the heterotic string, addres-sing in detail their construction, classi cation and phenomenological po-tential. Based on the insight gained from grand uni cation theories, wedevelop a successful strategy to search for models resembling the mini-mal supersymmetric extension of the standard model (MSSM) in II6orbifold compacti cations. We nd about 200 MSSM candidates with thegauge group and the exact spectrum of the MSSM, and supersymmetricvacua below the compacti cation scale. Among them, there are severalmodels with the following realistic features: R-parity, seesaw suppressedneutrino masses, and intermediate scale of supersymmetry breakdown.Post address: BONN-IR-2008-08Nussallee 12 Bonn University53115 Bonn Juni 2008Germany ISSN-0172-8741Towards Low Energy Physics from theHeterotic StringDissertationzurErlangung der DoktorwurdederMathematisch-Naturwissenschaftlichen FakultatderRheinischen Friedrich-Wilhelms-Universitatzu Bonnvorgelegt vonSaul Noe Ramos SanchezausMexiko StadtBonn 2008Angefertigt mit Genehmigung der Mathematisch-Naturwissenschaftlichen Fakultat der UniversitatBonnReferent: Prof. Dr. Hans-Peter NillesKorreferent: Prof. Dr. Albrecht KlemmTag der Promotion: 24.
