On the energy spectrum of the electroweak Pomeron

Abstract

In this paper we study the high energy behaviour of Electroweak Standard Model for a nonzero Weinberg angle ${\theta }_W$. We evaluate the spectrum of the electroweak pomeron and demonstrate that the leading intercept is given by ${\alpha }_{e.w.}4\ln 2$ and does not depend on the mixing angle ${\theta }_W$. Due to its very small numerical value, we conclude that the high energy behaviour of electroweak theory cannot be discussed without including the QCD Pomeron which, at sufficiently large energies, will dominate.
