软壁中的费米子质量体系

Fermion Mass Hierarchy from the Soft Wall

Antonio Delgado, David Diego

摘要:

我们开发了一个5D模型的电弱物理的基础上的一个非紧凑的翘曲额外的尺寸有限的长度,被称为软壁的情况下,所有的动力学自由度在5D散装传播。我们解决的运动方程,并找到允许的光谱,表明最轻的费米模式的质量表现为有效的4d汤川耦合常数的幂律,与指数是相应的费米5d体质量。正是这种非普遍的行为使我们能够再现标准模型(SM)费米子质量(从中微子到顶夸克)与非分级费米子体质量之间的分级。

英文摘要:

We develop a 5d model for ElectroWeak physics based on a non compact warped extra dimension of finite length, known as the soft wall scenario, where all the dynamical degrees of freedom propagate in the 5d bulk. We solve the equations of motion and find the allowed spectra, showing that the mass of the lightest fermionic mode behaves as a power law of the effective 4d Yukawa coupling constant, with the exponent being the corresponding fermionic 5d bulk mass. Precisely this non universal behavior allows us to reproduce the hierarchy between the Standard Model (SM) fermion masses (from neutrinos to the top quark) with non-hierarchical fermionic bulk masses.
