Asymptotic neutrino cross sections
Shifman M.A.
The asymptotic behavior of neutrino cross sections is discussed within the framework of field theory. It is shown that if strong interactions are described by a theory that has either asymptotic freedom or a fixed point, and if the weak interactions (in the four-fermion form) are taken into account only in first order, then the neutrino cross sections increase linearly with increasing neutrino energy.
