I have read several places that for a simple Higgs triplet model we can have either Y=0, +/- 2 This part I understand, because we have the relation Q=T3+Y/2 and any other Y values would therefore not allow for an electrically neutral Higgs. But what I don't understand is the claim that Y=+/- 2 is a complex triplet while only Y=0 can be real. Can somebody explain this?(adsbygoogle = window.adsbygoogle || []).push({});
