It would be nice if we could find some principle able to restrict the gauge symmetry.<br /><br />FFlorin Moldoveanuhttps://www.blogger.com/profile/01087655914212705768noreply@blogger.comtag:blogger.com,1999:blog-3832136017893749497.post-56687328542922679302014-09-08T14:58:50.810-04:002014-09-08T14:58:50.810-04:00Hi Florin,

I will try to get to that later.<br /><br />That electromagnetism is SU(2) at high energy energy is an interesting possibility. The EW interaction is then SU(2)_w x SU(2)_em at high energy. The interactions with fermions are as you say and one has to do some creative work with the Gel-Mann Nishijima formula for hypercharge. At low energy the center of the SU(2)_em breaks into U(1). <br /><br />This is a variation of the Pati-Salaam model. I did some work along these lines back in the 90s. I am not sure there is any experimental evidence for this. One prediction I came up with is another Z-like particle, what I called Z_γ, that comes from the oppositely charged parts of the SU(2)_em.<br /><br />LCLawrence Crowellhttps://www.blogger.com/profile/12090839464038445335noreply@blogger.com
