Hope some of the resident experts in particle physics can respond to it, because I'm unable to find a response to the question:
Is a Goldstone boson the same thing that a Nambu-Goldstone boson?
I suspect that is true because both particles are referred as massless, but I prefer the confirmation of some knowledgeable person

Never mind, I finally found that they are the same thing.
Curious fact: a majoron is a kind of Goldstone Boson
Goldstone bosons have spin 0.

A majoron is a goldstone boson by construction since it comes from the spontaneous breaking of a symmmetry (as any goldstone boson).
 

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}...
