A Could a CPL parametrization be included into Brans-Dicke model?

[fab13]

TL;DR

After doing some forecasts with w_0,wa CDM, I would like to know if i can keep the same structure of the code but with generating Matter power spectra of Brans-Dicke

I have studied up to now about forecasts to constrain cosmological parameters in the context of CPL( Chevallier-Polarski-Linder ) parametrization with w_0, ,w_a parameters in equation of state for cosmic fluid.

For this, I have used Matter power spectra ("fake data") generated by CAMB and CLASS codes.

Now, I have to study the Brans-Dicke model : I think about generating Matter power spectra with CLASS (or rather Hi-CLASS) which has an option to generate specific Matter power spectra dedicated to Brans-Dicke framework.

I would like to know if I could keep the CPL parametrization in Brans-Dicke model, i.e generating Brans-Dicke Matter power spectra and include them into the forecast code in order to assess constraints on classical cosmological parameters and also on w_0,w_a parameters.

Hello, could this post be transfered to "

Beyond the Standard Model Forum " forum ? , I think this would be more suitable​

Could anyone give me some clues or some elements of answer ? The 2 modified models could co-exist ?

Thanks
