I can't really understand why two higgs doublets are required inSUSY.
From the literature, I have found opaque explanations that saysomething along the lines of: the superpotential W must be aholomorphic function of the chiral supermutiplets and thus we needto introduce another chiral supermutiplet.
I also know that this is somehow related to an anomalycancellation. Can somebody help to make this a bit more clear?
