论文摘要
我们研究了Horndeski重力中厚的棕褐色溶液。在此设置中，我们找到了分析解决方案，将一阶形式主义应用于两个标量字段，在两个标量场中，第一个字段来自非最小标量量耦合，第二个字段是由于物质贡献部门所致。使用这些分析溶液，我们评估了具有四维几何形状的Horndeski重力中的对称厚的Brane溶液。在这样的设置中，我们评估了为Horndeski参数的任何值，将重力波动找到``几乎无质量的模式''。这些模式用于计算牛顿电位的校正，并评估极限四维重力。
We investigate thick brane solutions in the Horndeski gravity. In this setup, we found analytical solutions, applying the first-order formalism to two scalar fields where the first field comes from the non-minimal scalar-tensor coupling and the second is due to the matter contribution sector. With these analytical solutions, we evaluate the symmetric thick brane solutions in Horndeski gravity with four-dimensional geometry. In such a setup, we evaluate the gravity fluctuations to find ``almost massless modes'', for any values of the Horndeski parameters. These modes were used to compute the corrections to the Newtonian potential and evaluate the limit four-dimensional gravity.
