Empirical Neutrino Mass Matrix Related to Up-Quark Masses
Yoshio Koide
12 pages, 2 figures
(Submitted on 21 Mar 2008)

"A new approach to quark and lepton masses is proposed: the mass spectra originate in vacuum expectation values of U(3) flavor nonet (gauge singlet) scalars. As an offshoot of this approach, we find an empirical neutrino mass matrix which is described in terms of the up-quark and charged lepton masses and which leads to a nearly tribimaximal mixing without assuming any discrete symmetry."
Just posted. Enjoy

One general question is, if you only have the top mass, how do you seesaw?
 

Thread 'Toponium Discovered'

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...

Thread 'Dirac-Delta from Normalization of Continuous Eigenfunctions'

I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
