Detailed Description

Computes k factor for gluon fusion production.

The k factor is computed if the per-dataset configuration contains parameter "k_factor" and its value is "ggF". Otherwise a weight of 1 is returned for every event.

Member Function Documentation

double KFactorCorrection::HiggsMass

(

)

const

Computes mass of generator-level Higgs boson.

The Higgs boson is reconstructed from generarol-level leptons.

virtual double KFactorCorrection::NominalWeight

(

)

const [override, virtual]

Computes and returns the k factor for the current event.

The k factor is 1. if the correction is disabled.

Implements WeightBase.
