In the past three years some aspects of the duality in between representation theory of associative algebras and N=2 supersymmetric theories in four dimensions have proven to be crucial for understanding the so-called BPS-quiver theories. Very...

We introduce a method for computing conformal blocks of operators in arbitrary Lorentz representations in any spacetime dimension, making it possible to apply bootstrap techniques to operators with spin. The key idea is to implement the "shadow...

In this talk I will discuss a deformation of the CP^{N-1} sigma model. Bosonic and fermonic formulations of the deformed model will be presented and conditions for which the theory appears to be quantum integrability will be spelled out...

We present an alternative approach to low-energy supersymmetry. Instead of imposing R-parity we apply the minimal flavor violation (MFV) hypothesis to the R-parity violating MSSM. In this framework, squarks can be light and the proton long lived...
