     Modern String Theory Confronts Particle Physics and Black Holes

     Prof. Mirjam Cvetič, Physics Department, University of Pennsylvania, Philadelphia, USA

String theory, as the prime candidate for quantum unification of particle physics and gravity, sheds light on important fundamental questions such as the microscopic structure of black holes and the geometric origin of particle physics. We review these evelopments such as the introduction of extended objects - Dirichlet branes - nd highlight the important geometric role of these objects in deriving particle physics from string theory and review the geometric role these object play in elucidating the microscopic structure of black holes. We highlight the most recent progress made in deriving particle physics from F-theory, a geometric framework of string theory with Dirichlet branes at finite coupling. We also review recent progress made on studies of the internal structure of non-extremal black holes in string theory via introduction of the so-called subtracted geometry.
