Subject

The goal of this project is to advance theoretical predictions for a number of relevant benchmark processes for Higgs boson production at the LHC that combine higher-order QCD corrections and effects of higher-dimensional operators. For Higgs production in weak boson fusion and Higgs associated production we aim at a combination of NNLO QCD corrections and anomalous couplings. For Higgs pair production, NLO electroweak corrections will be included, for Higgs production in association with two jets the NLO QCD corrections with full top quark mass dependence will be calculated.

Research Topics

  1. Standard Model Effective Theory: QCD renormalization of the relevant effective operators
  2. Higgs coupling to vector bosons: associated $VH$ and weak boson fusion production with NNLO QCD corrections and higher-dimensional operators
  3. Yukawa couplings of light and heavy quarks: $q \bar q \to H$ and $gg \to H$ through NNLO QCD and the determination of light quarks Yukawa coupling
  4. Higgs+jet(s) production with higher-order corrections, quark mass effects, higher-dimensional operators and Higgs decays
  5. Electroweak corrections to Higgs boson pair production
