论文摘要
在这项工作中，我们研究了广义混合度量 - 帕拉蒂尼引力理论的标量张量表示中的5维BRANEWORLD场景。我们首先考虑一个纯粹由理论引力标量场支持的勃雷（Brane）模型，然后考虑其他不同的情况，在这些情况下，模型也得到了其他物质标量场的支持。我们研究了重力部门的稳定性，并表明这些模型都与度量的微小波动有关。特别是，在存在附加标量场的情况下，我们发现重力零模式的轮廓可以由模型的参数控制，也可以开发内部结构。
In this work, we study 5-dimensional braneworld scenarios in the scalar-tensor representation of the generalized hybrid metric-Palatini gravitational theory. We start by considering a model for a brane supported purely by the gravitational scalar fields of the theory and then consider other distinct cases where the models are also supported by an additional matter scalar field. We investigate the stability of the gravity sector and show that the models are all robust against small fluctuations of the metric. In particular, in the presence of the additional scalar field, we find that the profile of the gravitational zero mode may be controlled by the parameters of the model, being also capable of developing internal structure.
