标题： Solar system tests in covariant f(Q) gravity

摘要： 我们研究了协变$f(Q)$引力的太阳系限制。 协变$f(Q)$理论由度规和仿射联络描述，其中挠率和曲率都消失。 考虑一个包括更高非度量标量修正的模型$f(Q)= Q +\alpha Q^{n} - 2\Lambda$，我们推导出静态且球对称的解，这些解表示具有高阶修正的 Schwarzschild-de Sitter 解，对应于仿射联络的两种不同假设。 在所得时空解上，我们研究了近日点进动、光线偏折、Shapiro 延迟、卡西尼约束以及$f(Q)$引力中的引力红移。 我们利用太阳系的各种观测数据，在我们的$f(Q)$引力模型中，对参数$\alpha$施加了约束，其中包含$n=2, 3$。 显示英文摘要

摘要： We study the Solar System constraints on covariant $f(Q)$ gravity. The covariant $f(Q)$ theory is described by the metric and affine connection, where both the torsion and curvature vanish. Considering a model including a higher nonmetricity-scalar correction, $f(Q)= Q +\alpha Q^{n} - 2\Lambda$, we derive static and spherically symmetric solutions, which represent the Schwarzschild-de Sitter solution with higher-order corrections, for two different ansatz of the affine connection. On the obtained spacetime solutions, we investigate the perihelion precession, light deflection, Shapiro delay, Cassini constraint, and gravitational redshift in the $f(Q)$ gravity. We place bounds on the parameter $\alpha$ with $n=2, 3$ in our model of $f(Q)$ gravity, using various observational data in the Solar System.
