Does anybody know a good (short) reference which explains how a top-quark condensate acting like a "bound state Higgs" generates both fermion and W- / Z-masses?
 
Physics news on Phys.org
no idea?
 
There are a number of variants of what you are looking for:

Look for top quark condensate or Topcolor models.

A good set of lectures here:
arXiv:hep-ph/0203079

or perhaps read one of the original papers

Minimal dynamical symmetry breaking of the standard model. Phys. Rev., D41:1647, 1990.
 
thanks
 
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...
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}...
