Weak radiative corrections to dijet production at the LHC

TL;DR

This paper calculates weak radiative corrections to dijet production at the LHC, highlighting their significance at high energies due to logarithmic enhancements, and compares their impact on different distributions.

Contribution

It provides a comprehensive calculation of both tree-level and loop weak corrections to dijet production, emphasizing their importance at high energies.

Findings

Weak corrections can be large at high energies due to Sudakov logarithms.

Corrections to transverse-momentum distributions are about twice as large as those to invariant-mass distributions.

Tree-level electroweak contributions are comparable in size to loop corrections.

Abstract

We summarize the calculation of the weak corrections to dijet production at hadron colliders, comprising tree-level effects of O(\alpha_s\alpha,\alpha^2) and loop corrections of O(\alpha_s^2\alpha). Although suppressed by the small value of the coupling constant \alpha, the weak radiative corrections can become large in the high-energy domain due to the appearance of Sudakov-type and other high-energy logarithms. Generally the corrections to the transverse-momentum distributions are larger by approximately a factor of two compared to the corresponding reach in the invariant-mass distributions, because the invariant-mass distributions are not, unlike the k_T distributions, dominated by the Sudakov regime at high scales. The electroweak tree-level contributions are found to be of the same generic size as the loop corrections.
