On the energy spectrum of the electroweak Pomeron

TL;DR

This paper analyzes the energy spectrum of the electroweak Pomeron in the Standard Model, revealing that its leading intercept is independent of the Weinberg angle and highlighting the dominance of QCD effects at high energies.

Contribution

It provides a calculation of the electroweak Pomeron spectrum and shows the leading intercept's independence from the mixing angle, offering insights into high energy electroweak behavior.

Findings

Leading intercept is given by α_e.w. 4 ln 2

Intercept does not depend on the Weinberg angle θ_W

Electroweak effects are overshadowed by QCD at high energies

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 $\alpha _{\rm e.w.}4 \ln 2$ 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.
