Description
We study the effects of dimension six operators on the Higgs decay into
four lepton channel. The calculation of new matrix element is performed
in the Higgs basis and it is implemented in a Monte Carlo event generator.
The code also allows the calculation in other popular choices of basis for
the dimension six operators. We have considered all the relevant operators,
both the CP-even and CP-odd operators, which contribute to this decay
channel. Choosing some benchmark values for the parameters of the Higgs
basis, we compare our predictions for partial decay width and some important
kinematic distributions with the corresponding NLO(EW) SM predictions.
