TL;DR

The Tevatron-for-LHC Report: Higgs surveys how Tevatron experience with backgrounds, techniques, and calculations can inform Higgs measurements at the LHC. It compiles up-to-date SM and MSSM Higgs production cross sections for both collider environments, using NNLO QCD for the dominant processes and an effective coupling framework for MSSM predictions across four benchmark scenarios. The document emphasizes precise signal and background predictions to enable robust discovery and coupling measurements across multiple channels. By integrating theoretical advances with experimental reviews from Tevatron and LHC contexts, it advances the understanding of electroweak symmetry breaking and guides future analyses at both facilities.

Abstract

The search for Higgs bosons in both the standard model and its extensions is well under way at the Tevatron. As the integrated luminosity collected increases into the multiple inverse femptobarn range, these searches are becoming very interesting indeed. Meanwhile, the construction of the Large Hadron Collider (LHC) and its associated experiments at CERN are nearing completion. In this TeV4LHC workshop, it was realized that any experience at the Tevatron with respect to backgrounds, experimental techniques and theoretical calculations that can be verified at the Tevatron which have relevance for future measurements at the LHC were important. Studies and contributions to these efforts were made in three broad categories: theoretical calculations of Higgs production and decay mechanisms; theoretical calculations and discussions pertaining to non-standard model Higgs bosons; and experimental reviews, analyses and developments at both the Tevatron and the upcoming LHC experiments. All of these contributions represent real progress towards the elucidation of the mechanism of electroweak symmetry breaking.

  • Figure 2.2.1: Higgs-boson production cross sections (fb) at the Tevatron ($\sqrt{s}=1.96$ TeV) for the most relevant production mechanims as a function of the Higgs-boson mass. Results for $gg \to h$, $q\bar{q}\to Vh$, $b\bar{b} \to h$ are at NNLO in the QCD expansion. Weak boson fusion ($qq \to qq h$) and $t\bar{t}$ associated production are at NLO accuracy.
  • Figure 2.2.2: Higgs-boson production cross sections (fb) at the LHC ($\sqrt{s}=14$ TeV) for the most relevant production mechanims as a function of the Higgs-boson mass. Results for $gg \to h$, $q\bar{q}\to Vh$, $b\bar{b} \to h$ are at NNLO in the QCD expansion. Weak boson fusion ($qq \to qq h$) and $t\bar{t}$ associated production are at NLO accuracy. Single-top associated production ($qb \to qth$) is at LO.
