D-branes in String Theory and Particle Physics

Professor Dr. Mirjam Cvetič

Department of Physics and Astronomy
University of Pennsylvania, Philadelphia, U. S. A.

Abstract: We review developments leading to the unification of string theories (M-theory), with an emphasis on particle physics implications. We introduce extended objects - Dirichlet branes - and highlight an important geometric role that these objects play in deriving particle physics from string theory. Constructions of string solutions with Dirichlet branes, that have features of the Standard Model with three families of quarks and leptons, are reviewed. We also highlight recent developments for calculations of perturbative and non-perturbative (D-brane instanton) Yukawa couplings that may lead to realistic fermion mass hierarchies.

Seminarsko predavanje (v angleškem jeziku) bo v petek 21. septembra 2007 ob 15:15 uri v seminarski sobi CAMTP na Krekovi 2, pritličje desno. Vljudno vabljeni vsi zainteresirani, tudi študentje.
