Pointlike electrons and muons and the nature of neutrinos

Abstract

We show that the form factor of an electron or a muon is unity for the modulus of the momentum transfer away from the Hagedorn temperatures $T_0^e\sim m_e$ and $T_0^{\mu }\sim m_{\mu }$ and lower than the hadronic Hagedorn temperature $T_0^{QCD}\sim m_{\pi }$. The structure of the electron or the muon is resolved for momemtum transfers comparable to $T_0^{e,\mu }$. This is seen in scattering experiments performed in the 1950s, 1960s, and early 1970s to test the validity of QED. We interprete center-vortex loops with no self-intersection, occurring in the confining phases of each SU(2) gauge-theory factor, as {\sl Majorana} neutrinos. We offer a possible explanation for a contribution to ${\Lambda }_{cosmo}$ not generated by the so-far nonconfining, strongly interacting gauge theory SU(2)${}_{CMB}$.
