Constraints on Scalar-Tensor Theory of Gravity by Solar System Tests

We study the motion of particles in the background of a scalar-tensor theory of gravity in which the scalar field is kinetically coupled to Einstein tensor. We constrain the value of the derivative parameter $z$ through solar system tests. By considering the perihelion precession we obtain the constrain $\sqrt{z}/m_p > 2.6\times 10^{12}$ m, the gravitational red-shift $\frac{\sqrt{z}}{m_{p}}>2.7\times10^{\,10}$ m, the deflection of light $\sqrt{z}/m_p > 1.6 \times 10^{11}$ m, and the gravitational time delay $\sqrt{z}/m_p > 7.9 \times 10^{12}$ m; thereby, our results show that it is possible to constrain the value of the $z$ parameter in agreement with the observational tests that have been considered.
