The present acceleration of the Universe strongly indicated by recent observational data can be modeled in the scope of a scalar-tensor theory of gravity. We show that it is possible to determine the structure of this theory along with the present density of dustlike matter from two observable cosmological functions: the luminosity distance and the linear density perturbation in the dustlike matter component as functions of redshift. Explicit results are presented in the first order in the small inverse Brans-Dicke parameter omega(-1).

Large‐scale cosmic microwave background anisotropies and dark energy (2003, background): “These models might be realized in non-minimally coupled scalar field dark energy models (Amendola 1999; Boisseau et al. 2000) or k-essence with non-canonical kinetic terms (ArmendarizPicon, Mukhanov & Steinhardt 2000).”
Exploring the expanding Universe and dark energy using the statefinder diagnostic (2003, background): “Models based on scalar-tensor gravity (Boisseau et al. 2000) can have w < −1, so too can braneworld models (see Sahni & Shtanov 2002 for a discussion of this issue and Alam & Sahni 2002 for a comparison of braneworld models with observational data).”
Imperfect Dark Energy from Kinetic Gravity Braiding (2010, background): “Thus in this respect, kinetic braiding exhibits similar phenomenology to models with explicit nonminimal coupling to gravity, which also allow one to have a classically stable crossing of the phantom divide in scalar-tensor theories [85, 86, 87, 88].”
Cosmology and Fundamental Physics with the Euclid Satellite (2012, background): “Scalar-tensor theories [1242, 628, 629, 370, 291, 292, 1243, 1184, 945, 470, 199, 1010, 944, 1051, 854, 948, 949, 274, 70] extend GR by introducing a non-minimal coupling between a scalar field (acting also as dark energy) and the metric tensor (gravity); they are also sometimes referred to as ‘exte”
MODEL-INDEPENDENT EVIDENCE FOR DARK ENERGY EVOLUTION FROM BARYON ACOUSTIC OSCILLATIONS (2014, methodology): “More generally, this behavior occurs in modified gravity (e.g., in scalar-tensor gravity) when the effective gravitational constant Geff (z) < Geff (0) ≡ G, if we define ρDE(z) using the present value of κ in Equation (7) following Boisseau et al. (2000); Sahni & Starobinsky (2006).”
The dS/CFT Correspondence and the Big Smash (2001, background): “Theoretical efforts to come to terms with this possibility have largely focused on scalar fields, particularly non-minimally coupled scalars [2][ 5 ][6][7].”
Growth factor in $f(T)$ gravity (2010, background): “Although dark energy scenario [1] is the most popular one among them, ones have considered some models based on infra-red modifications to general relativity (GR), such as scalar-tensor theories [2], f(R) gravity [3] and braneworld models [4].”
