Flavor hierarchies, flavor anomalies, and Higgs mass from a warped extra dimension

TL;DR

This paper presents a unified model explaining B-meson anomalies, flavor hierarchies, and the Higgs mass using a warped extra dimension framework with hierarchical couplings and a pseudo-Nambu-Goldstone Higgs.

Contribution

It introduces a complete theory of flavor based on a warped fifth dimension, unifying quarks and leptons and addressing multiple fundamental problems.

Findings

Models explain B-meson anomalies at TeV scale.

Hierarchical couplings mimic Standard Model Yukawas.

Higgs emerges as a pseudo-Nambu-Goldstone boson.

Abstract

The recent B-meson anomalies are coherently explained at the TeV scale by 4321 gauge models with hierarchical couplings reminiscent of the Standard Model Yukawas. We show that such models arise as the low-energy limit of a complete theory of flavor, based on a warped fifth dimension where each Standard Model family is quasi-localized in a different brane. The Higgs is identified as a pseudo-Nambu-Goldstone boson emerging from the same dynamics responsible for 4321 symmetry breaking. This novel construction unifies quarks and leptons in a flavor non-universal manner, provides a natural description of flavor hierarchies, and addresses the electroweak hierarchy problem.
