Abstract
The problem of defenition of the post-Newtonian parameter γ in massive scalar-tensor theories is considered. We demonstrate an equivalent correspondence between the post-Newtonian parameter γ and the parameter appearing in the equation of a null geodesic in massive scalar-tensor theories. We show that massive scalar-tensor theories can be distinguished from general relativity via the Shapiro time delay. All calculations are performed for hybrid metric-Palatini f(R)-gravity for the sake of illustration. The expression for Shapiro time delay in hybrid f(R)-gravity is obtained for the first time.
