I am also working (and I am going to continue this study) on 2 dimensional QCD2(N = ) and other "toy" models. I believe that toy models may help us to understand the nature of chiral symmetry breaking phenomena.
I am also working in the area where the particle physics and the theory of gravity overlap. I believe that this field will be the most exciting in the near future.
