Does anyone know the peak(or the energy at which the flux is the greatest) of the GCR spectrum? And a quotable source for that. I am pretty sure it is in the 1-10 GeV/nucleon range.
thanks

This page says thaty the GCR (Galactic cosmic Ray) spectrum peaks near 300 MeV

Actually that data seems to be the particle count through 1.27 mm of Aluminum. Although I am trying to look up their reference for it. So it appears that I am still trying to find what the actual peak of the GCR is. In Gaisser's book he has a couple of plots but I am trying to verify them to myself since they are slightly misleading I think.
So if anyone can offer some more help I would appreciate it.
Cheers
 

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}...
