The "angle with 1,1,1", sqrt(2/3), has really two different pieces: the sqrt(3) comes from the number of families, and the sqrt(2), is the size of the symmetry breaking, as it appears very naturally in eq 46 of Brannen's.Alejandro Riverohttps://www.blogger.com/profile/16181521111080562335noreply@blogger.comtag:blogger.com,1999:blog-7307840825023135484.post-34045426111000463192010-10-24T09:16:08.312+13:002010-10-24T09:16:08.312+13:00Alejandro, I believe it was Hans de Vries who firs...Alejandro, I believe it was Hans de Vries who first pointed the triangle out, some years ago.

The most recent estimates for u and d quark masses are 5 and 20 MeV.<br /><br />I assume that the order of masses is t,u, c and b,d, s and unit is GeV.<br /><br /><br />For d the prediction would be at the lower boundary of 2-15 MeV range. For s 71.639 MeV is below 100-130 MeV. For b prediction would be in the required range.<br /><br />For U type quarks the predictions would be by order of magnitude too small as compared to the lower bounds.Matti Pitkänenhttp://tgd.wippiespace.com/public_html/noreply@blogger.comtag:blogger.com,1999:blog-7307840825023135484.post-71232272235316806222010-10-21T17:59:25.985+13:002010-10-21T17:59:25.985+13:00So the bigger triangle is completely defined by th...So the bigger triangle is completely defined by the ansatz of phases: sending the $2/9$ for leptons to $2/27$ for the quarks.
