Dear all,

I calculated the mass stopping power of muon but the result was 1.4 MeV.g^-1.cm^2.
I calculated by BEthe-Bloch formula.
I think it is wrong. since I looked up in the books and internet, this value is about 2 MeV.g^-1.cm^2.
Can you help me. I also send the excel file as below.

hmmm... If you could explain what you actually show in the excel it would be easier for someone to help you. That's a common fact in everything [of course you know what you've been doing in the excel because you did it, but someone else doesn't know and you have to explain somehow how you moved and what did you do]

eg. did you use this formula?

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}...
