论文摘要

在此手稿中,我们讨论了跨越branewords模型上的旋转$ \ frac {1} {2} $ field的限制。最近,在(EUR.PHYS.J.C 80(2020)5,432)中,我们研究了标准模型(SM)字段与Einstein方程式在Braneworlds上定位的一致性。在该论文中,我们讨论了纺纱场约束的一致性,并使用$ \ Mathcal {l} _ {int} \ propto f(y)\ bar单ψ$给出的类似Yukawa的互动,我们获得了该函数必须定义为$ f(y)\ propto e^e^e^{ - a} a}'''''''''''''''''''标量函数的这种形状来自于以下要求,即旋转$ \ frac {1} {2} $(零模式)本地化无法修改批量计量。这样可以确保保留重力的限制。在当前的手稿中,我们找到一个可以生成此相互作用的协变量标量耦合函数。这提供了一种新的机制,可以将费米恩场定位在木板上。我们还讨论了巨大的模式,并发现了一些重力配置,其中有限制和离散的大规模模式。

In this manuscript, we discuss the confinement of the spin $\frac{1}{2}$ field on a plethora of branewords models. Recently, in (Eur.Phys.J.C 80 (2020) 5, 432), we studied the consistency of the Standard Model (SM) fields localization on braneworlds with the Einstein equation. In that paper, we discussed the consistency of the spinor field confinement and, by using a Yukawa-like interaction given by $\mathcal{L}_{int}\propto f(y)\barΨΨ$, we obtained that the function must be defined as $f(y)\propto e^{-A}A'$. This shape of the scalar function emerge from the requirement that the spin $\frac{1}{2}$ (zero-mode) localization cannot modify the metric on bulk. This ensures that the confinement of gravity on the brane is preserved. In the present manuscript, we find a covariant scalar-coupling function that can generate this interaction. This provide a new mechanism for localizing fermion fields over the brane. We also discuss massive modes and we found some gravitational configuration where there are confined and discretized massive modes.
