Do SUSY particles have antiparticles counterparts?

[alvarogz]

Well, all of this is theoretical, but I asked myself this because I never heard about antimatter in a SUSY particle context.

Presumably they do, but until a SUSY particle is actually discovered we can't be certain.

The existence of antiparticles is a requirement of Lorentz invariance. It wouldn't typically be discussed in a SUSY reference because it's QFT background material that the reader could be expected to be familiar with.
