Fermion mass hierarchy in a multiple warped braneworld model

TL;DR

This paper explores how a multiple warped spacetime model can naturally generate the fermion mass hierarchy observed in the Standard Model without fine-tuning, by analyzing the effects of large warping on fermion masses.

Contribution

It introduces a novel multiple warped braneworld model that explains fermion mass splitting through geometric warping, avoiding hierarchy issues among moduli.

Findings

Achieves $10^{16}$ order warping between Planck and visible branes

Determines parameter values consistent with observed fermion masses

Shows mass splitting arises naturally from geometric warping

Abstract

A geometric understanding of the origin of mass hierarchy among the standard model fermions have been addressed in a multiple warped spacetime. We show that the requirement of $10^{16}$ order warping between the Planck and the visible branes without creating any significant hierarchy among the moduli results into splitting of fermion masses in the standard model. Values of the various parameters of the extra dimensional model and the corresponding fermion masses are determined.
