In recent years we have come to appreciate that the microscopic dynamics of quantum field theory leave behind indelible signatures in long range, near-equilibrium phenomena. We will describe an effective field theory which captures some of these...

In this talk I study the one loop effective action for a class of higher spin fields by using a first-quantized description. The latter is obtained by considering spinning particles, characterized by an extended local supersymmetry on the worldline...

Regge theory is the idea that physical observable in quantum theory can be defined for complex angular momentum. Its main result is the possibility to analyze an amplitude in one channel, in terms of the states exchanged in another channel, in...

A summary of results on relativistic local quantum theory and sketches of some of the important mathematical ideas underlying the theory are presented. Details can be found in the book of Rudolf Haag and various review papers (in particular ones...

TeV scale Wino, provides a possible Dark Matter candidate in the context of the Minimal Supersymmetric Standard Model. Such a dark matter candidate evades all current direct detection and collider bounds and can only be probed through its...

Anomalous dimensions of any local operators in planar N=4 SYM are a unique example of a non-BPS quantitiy, defined by genuine 4D Feynman graphs including all gluon interactions, which can be computed exactly, in principle at any 't Hooft coupling...
