In this talk I will discuss recent work constructing heterotic standard models by compactifying on smooth Calabi-Yau three-folds in the presence of purely Abelian internal gauge fields. The simple construction of these models allows for a large...

We consider unitary Conformal Field Theory in dimensions D higher than two with a finite central charge. We assume that CFT contains conserved current of spin higher than two. We analyze the consequences of this fact. We focus on the case of D=3 and...

I will describe a new family of geometric flows which describe holographic RG evolution of metric data for M5 or D3 branes compactified on a Riemann surface. A global existence proof establishes the existence of solutions interpolating between an...

I will present the open string tree level amplitude of massless states to any number of external legs. It turns out that the kinematic factor of disk amplitudes is entirely captured by the underlying SYM field theory, i.e. that all the dependence on...
