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)
