Nuclear Physics & RIKEN Theory Seminar

"Mass-Gaps, Gluon mass-terms and Supersymmetry in D=2+1"

Presented by Abhishek Agarwal, American Physical Society

Friday, January 20, 2012, 2:00 pm — Small Seminar Room, Bldg. 510

In this talk - based on work in collaboration with V.P.Nair and A. Fayyazuddin - I'll focus on the mechanism of the dynamical generation of mass-gaps in the spectrum of three dimensional gauge theories in a gauge invariant formalism; originally due to Kim, Karabali and Nair. I will be particularly interested in addressing the interplay between dynamical mass-gaps and supersymmetry and present a first principles explanation for the absence of mass-gaps for N >2 SUSY for Yang-Mills theories [without additional hypermultiplets] in D=3. I will also discuss the compatibility of mass-gap with minimal supersymmetry and discuss how these results square with many expectations based on other non-perturbative approaches. Finally I will try to comment on a possible generalization of the mechanism of dynamical mass-generation to a manifestly Lorentz invariant framework.
