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...

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...

We introduce a new numerical algorithm based on semidefinite programming to efficiently compute bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and N=1 superconformal field theories. Using our algorithm, we...

An SO(3) subgroup of the conformal group in four dimensions can be used to study aspects of hadronic collisions. Two examples are the hydrodynamic flow at times well before freeze-out and the characterization of initial state in terms of a...
