Model building• In the last years, there are several approaches towards thesearch for the Standard Model in String theory.• However, non of them successfully describes all features of theSM or MSSM... We are working on this...• Today, several new techniques have been established and can beapplied in this task.• Instead of a blind search, a better technique would be to focusin string vacua with some acceptable phenomenological criteria.• In this talk, we will focus on the mass-terms and hierarchy insuch models.Sunday, July 5, 2009
