Ongoing and upcoming cosmological surveys will significantly improve our ability to probe the equation of state of dark energy, $w_{\rm DE}$, and the phenomenology of Large Scale Structure. They will allow us to constrain deviations from the $\Lambda$CDM predictions for the relations between the matter density contrast and the weak lensing and the Newtonian potential, described by the functions $\Sigma$ and $\mu$, respectively. In this work, we derive the theoretical prior for the joint…
