Differential Higgs+jet production in bottom quark annihilation and gluon fusion

TL;DR

This paper compares Higgs production via bottom quark annihilation and gluon fusion, analyzing jet distributions and the validity of the heavy-top approximation at high precision levels.

Contribution

It provides detailed differential distributions and assesses the accuracy of the heavy-top limit in Higgs production calculations at NNLO and NLO.

Findings

Jet distributions in bottom quark annihilation are characterized at NNLO and NLO.

The heavy-top approximation's accuracy is evaluated at O(α_s^4) with higher order terms.

Differential quantities show the limits of the heavy-top approximation.

Abstract

We present recent developments concerning Higgs production in bottom quark annihilation and gluon fusion. For bottom quark annihilation, we show the transverse momentum distribution of the associated jets. Furthermore, we discuss the distribution of events into n-jet bins for n=0 and n>0 at NNLO and NLO, respectively. For gluon fusion, the quality of the heavy-top limit for differential quantities at O(\alpha_s^4) is studied by taking into account higher order terms in the 1/m_{top} expansion.
