I am reading ahead for my Group Theory introduction to QFT and I have a question about the dual representation. If the dual representation is the same as the ordinary representation, that is to say the ordinary representation is "real", how do we represent anti-particles in this case? This seems to be the case for SU(2), which is the gauge group for weak interactions.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks,

Ryan
