Effects of bottom quark induced processes on polarized $W^+W^-$ production at the LHC at NLO

TL;DR

This paper investigates how bottom-quark induced processes influence polarized W+W- production at the LHC, emphasizing the significance of these effects at NLO accuracy, especially for doubly-longitudinal polarization.

Contribution

It provides a detailed analysis of polarized cross sections at NLO, highlighting the impact of bottom-quark processes and their importance after top-quark subtraction.

Findings

Bottom-quark induced effects are more significant for doubly-longitudinal polarization.

Effects are more sizable after subtracting on-shell top-quark contributions.

Results are presented at NLO QCD+EW accuracy.

Abstract

In this report we discuss the definition of the polarized cross sections of the inclusive $W^+W^-$ production at the LHC. Results at the level of next-to-leading order (NLO) QCD+EW accuracy, published in our recent paper, are presented to highlight the effects of bottom-quark induced processes. Compared to the unpolarized case, the bottom-induced effects after the subtraction of the on-shell top-quark contribution are more sizable for the doubly-longitudinal polarization.
