Domain Walls in Supersymmetric QCD

Jesús Moreno

I.E.M. (C.S.I.C.)

We consider domain walls that appear in supersymmetric QCD with N_f < N_c massive flavours. In particular, for N_f=1 we explicitly construct the domain walls that interpolate between vacua labeled by i and (i+1). We show that these solutions are Bogomol'nyi-Prasad-Sommerfield (BPS) saturated for any value of the mass of the matter fields. This fact allows us to evaluate the large mass limit of these domain walls. We comment on the relevance of these solutions for supersymmetric gluodynamics.

The almuerzo-seminario is intended to be an informal seminar and an open forum for discussion.

You are wellcome to bring your own bocata (sandwich), or coffee or tea.
