k-epsilon model - k term in the U-equation

I am having a close look at the k-epsilon model implemented for incompressible flows in Openfoam.
in the following piece of code:
tmp<fvVectorMatrix> kEpsilon::divDevReff(volVectorField& U) const
- fvm::laplacian(nuEff(), U)
The k term in the Boussinesq eqauation ( 2/3 * k * delta_ij ) does not appear.
Where can I find this term in the implementation?
Thanks for your help!

You can find it in the file kEpsilon.C. I made a copy of it here:
I see that the minus sign is reversed ~? maybe it is multiplied with minus somewhere else !!!!!
