The LHC data are severely constraining natural theories of electroweak symmetry breaking.

An important part of the constraints comes from the fact that typically the partners of the top quark in carry color and can be profusely produced at hadron...

Plasma-filled magnetospheres can extract energy from spinning black holes and power a variety of observed astrophysical phenomena. These magnetospheres are described by the highly nonlinear equations of force-free electrodynamics, or FFE. Typically...

We find an asymptotic solution for two-, three- and, to some extent, multi-point correlators of local gauge-invariant operators, in a lower-spin sector of massless large-N QCD (and of n=1 SUSY YM), in terms of glueball and meson propagators, in such...

I will discuss some aspects of three-dimensional topological Chern-Simons theories with a Lie supergroup as a gauge group. These theories are similar to ordinary Chern-Simons, but also have some distinctive features. I will describe, how one can...

The topic of this seminar is the simplification of strongly interacting quantum
field theory at large J, where J is the quantum number of a state
under some symmetry group such as angular momentum or a global charge. As an example, I will review...
