Upper Bound on Neutrino Cross Sections
Abstract
Asymptotic bounds on the total cross sections of neutrino (weak) scattering processes are obtained. It is shown that the elastic neutrinoneutrino cross section obeys the following bound in the high energy region: sigma sub T (S) equals ImF(S,0)/S is less than or equal to const. (LogS) squared. Assumptions of analyticity, crossing, unitarity, polynomial boundaries, and a zerocondition on the absorptive part of the scattering amplitude, are used to obtain this bound.
