Asymmetrical braneworlds and the charged lepton mass spectrum

TL;DR

This paper proposes a braneworld model with an asymmetric warp factor to explain the charged lepton mass spectrum, successfully reproducing the Koide mass relation among electron, muon, and tauon.

Contribution

It introduces a novel 5+1-dimensional braneworld scenario with asymmetrical warping to derive lepton mass ratios, aligning with Koide's empirical formula.

Findings

Reproduces the Koide mass relation

Achieves proper mass fractions for leptons

Proposes a new braneworld mechanism for mass spectrum

Abstract

A braneworld mechanism for explaining the mass spectrum of the charged leptons is proposed. Based on the existence of an asymmetric warp factor for a $5+1$-dim braneworld scenario, the proper fractions between the masses of the electron, muon and tauon are achieved. As a straightforward consequence, our results coincide with the Koide's mass formula.
