Abstract

In these proceedings, we present results for Higgs production at the LHC via gluon fusion with triple real emission corrections and the validity range of the heavy-top effective theory approximation for this process. For a general CP-violating Higgs boson, we show that bottom-quark loop corrections in combination with large values of tan β significantly distort differential distributions.

Highlights

Higgs production in association with two jets via gluon fusion (GF) is a promising channel to measure the CP-properties of the recently found new scalar boson [1, 2] with mass of 126 GeV
The azimuthal angle correlations lead to a distinguishable spectrum [3, 4] sensitive to (1) the CP-nature of the Higgs particle, shifting the positions of the minima/maxima, (2) the Yukawa couplings, which change the normalization of the cross sections, (3) parameters in theories beyond the Standard Model (BSM), like tan β, which can significantly distort phenomenologically important differential distributions
Results for integrated cross sections and differential distributions are presented at the LHC for the sub-process gg → gggΦ

Summary

Introduction

Higgs production in association with two jets via gluon fusion (GF) is a promising channel to measure the CP-properties of the recently found new scalar boson [1, 2] with mass of 126 GeV. Higgs masses lower than the top-quark mass This approximation provides no predictions for bottom-quark induced loop contributions which can be relevant in BSM scenarios, e.g. due to a strong enhancement via tan β = vu/vd, the ratio of two vacuum expectation values, appearing in two Higgs doublet models (2HDM), like the Minimal Supersymmetric Standard Model. In these proceedings, we show results for the production of a general CP-violating Higgs boson in association with three jets via GF at LO beyond the heavy top-quark limit approximation, presented in Ref.
