Flavour anti-$k_\text{T}$ algorithm applied to $Wb\bar{b}$ production at the LHC

TL;DR

This paper applies a new flavoured anti-$k_T$ jet algorithm to $Wb\bar{b}$ production at the LHC, providing NNLO QCD predictions that align well with CMS data and exploring the algorithm's parametric effects.

Contribution

It introduces the flavoured anti-$k_T$ algorithm to $Wb\bar{b}$ production and compares its effects with the standard flavour-$k_T$ algorithm at NNLO accuracy.

Findings

NNLO QCD corrections are significant.

Good agreement with CMS data.

Comparison of flavoured algorithms shows parametric effects.

Abstract

We apply the recently proposed flavoured anti-$k_{\text{T}}$ jet algorithm to $Wb\bar{b}$ production at the Large Hadron Collider at $\sqrt{s}=8$ TeV. We present results for the total cross section and differential distributions at the next-to-next-to-leading order (NNLO) in QCD. We discuss the effects of the remaining parametric freedom in the flavoured anti-$k_{\text{T}}$ prescription, and compare it against the standard flavour-$k_{\text{T}}$ algorithm. We compare the total cross section results against the CMS data, finding good agreement. The NNLO QCD corrections are significant, and their inclusion substantially improves the agreement with the data.
