Hi !

I study nuclear reactions due to electron beam. In simulation (GEANT4), I note, whatever incident energy (10 MeV < E < 1 GeV), the primary electron is not absorbed and continues after the interaction.
This is not the case for protonuclear, photonuclear or neutronuclear reaction...!
What causes this difference ?

Thanks in advance !

Protons and neutrons can join a nucleus, photons can disappear. Electrons cannot - neglecting the weak interaction there will always be an electron around. It can get bound to one of the nuclei involved in the interaction, but that is a rare process.

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}...
