TOPICS IN SUPERSYMMETRIC GAUGE THEORIES AND THE GAUGE-GRAVITY DUALITY

EDALATI AHMADSARAEI, MOHAMMAD

Abstract Details

2007, PhD, University of Cincinnati, Arts and Sciences : Physics.
In this thesis we use supersymmetry and the gauge-gravity duality to shed light on some dynamical features of strongly-coupled non-Abelian gauge theories. In the first half of the thesis, we consider singular superpotentials of four dimensional N=1 supersymmetric QCD and show that they must exist. In particular, using some non-trivial consistency checks, we show that these superpotentials, albeit singular, are perfectly sensible, and can be used to reproduce in a simple way both the low energy effective dynamics as well as some special higher-derivative terms. In the second half of the thesis, we investigate the behavior of timelike, spacelike and Euclidean stationary string configurations on a five-dimensional AdS black hole background which, in the context of the gauge-gravity duality, correspond to quark-antiquark pairs steadily moving in an N=4 supersymmetric Yang-Mills thermal bath. We find that there are many branches of solutions depending on the quark velocity and separation as well as on whether Euclidean or Lorentzian configurations are examined. Such solutions can, in principle, be used to determine some transport properties of strongly-coupled N=4 thermal bath.
