Now I am confused. In susy theories there are chiral superfields as well as vector superfields, completely independent of interactions. (http://en.wikipedia.org/wiki/Supersymmetric_gauge_theory). Chiral fields are defined by \bar{D} \Phi=0. Vector fields one the other hand are identical to their...

Thanks for all your thoughts.

Thanks. According to the reference hep-th/9903387 vector-like is used synonymously with non-chiral. Which means that left and right components transform differently under SU(2) x U(1). But what if these groups are not present? What would be the distinction between chiral and non-chiral matter...

Sure, one place I encountered it is here: http://arxiv.org/abs/1001.1129

What is "vector-like" matter? Hi, can someone please tell me what vector-like matter is? meha

Hello, suppose you start with Yang Mills theory with some gauge group G, for example SU(5). Then you turn on a gauge bundle, say a U(1) bundle, and the group breaks down. I know that from hearsay but I wonder how would you describe that explicitly in formulas? meha
