Radiation in gg->H: comparison

Plots

  • Higss Masses: 120, 200, 400
  • Single Inclusive: H pT, H eta
  • Jets (fast-jet: anti-kT? kT? ... ?)
    • Single-Jet distributions
      • Jet rates
      • Jet pT distributions
      • Jet eta distributions
      • Jet Masses
    • 2-jet distributions
      • Delta(eta), Delta(R)
      • Jet Rate Ratios
    • Pathological Phase Space Points
      • Higgs + >= 2 jets at low Higgs pT
      • Hierarchies: One high scale + >= 2 objects at lower scale, for a small and a large scale separation

Tools

  • MC@NLO (Gunther)
  • POWHEG (Keith, Carlo)
  • PYTHIA (Steve)
  • MLM Matched (Fabio + Roberto Chierici)
  • CKKW (Stefan H. + Jan W.)
  • MCFM (H+X, H+1 jet; H+2 jets + X) (John)

Radiation in WBF: comparison

As above, modulo

  • WBF
    • Cuts: 2 Jets with pT > 0.4 in opposite hemisphere and Delta(y) > Delta(y)_min = 4.0
    • Observables:
      • Jet rates vs Delta(y) (for which jet pT?)
      • Ratios of jet rates
      • pT of jets
      • Delta(eta) jof ets
      • Decorrelation
      • Zeppenfeld Plot

Radiation in gg->H: mt finite vs mt->infty

  • Higgs + 1 Jet (MCFM) LO + finite mt
  • Higgs + 2 jets (VBF@NLO) LO + finite mt
  • Parton-Level plots
    • pT Higgs, eta
    • pT of the leading jet
    • Decorrelation
  • (Jeppe)

Radiation in W+jets

  • W + >= 2 jets
  • <cos(phi)> vs Delta(y) for various kinds of approaches
  • (Steve)
