论文摘要
我们研究了标量调整的重力理论的颗粒运动，其中标量场在动力学上耦合到爱因斯坦张量。我们通过太阳系测试来限制衍生参数$ z $的值。通过考虑圆锥体进料，我们获得了约束$ \ sqrt {z}/m_p> 2.6 \ times 10^{12} $ M，重力红移$ \ frac {\ sqrt {\ sqrt {z}}}} $ \ sqrt {z}/m_p> 1.6 \ times 10^{11} $ m，重力时间延迟$ \ sqrt {z}/m_p> 7.9 \ times 10^{12} $ m;因此，我们的结果表明，可以与已考虑的观察性测试一致限制$ z $参数的值。
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.
