hello all


It's probably already been noted but... have people seen the paper hep/th-0810.3328? "A simple introduction to particle physics"?

It looks like a very nice introduction to the maths behind the development of particle physics for advanced undegraduates and experimental physicists.

I'm looking forward to the other accounts in the series (even if I don't believe in string theory - do I sound a bit condescending? oops I don't want to! I just believe in LQG instead!)

Yeah, looks really good! Thank you, I look forward to the other too.

(must buy new tones for my printer hehe)

btw, we have section for tutorials, this will probably be moved to that section.

Thank you again for your contribution.
 
thanks for your contribution but try your best if you like particle physics, it is funny and difficult.
 
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}...
