Bulk gauge and matter fields in nested warping: I. the formalism

TL;DR

This paper develops a formalism for extending Standard Model gauge bosons and fermions into a six-dimensional doubly-warped bulk, offering a way to address issues like flavor-changing neutral currents and introduce new phenomenological phases.

Contribution

It introduces a novel formalism for bulk fields in a doubly-warped six-dimensional model, expanding beyond previous single-warp scenarios.

Findings

The model naturally avoids TeV-mass graviton constraints.

It proposes two distinct phenomenological phases.

Addresses flavor-changing neutral current problems.

Abstract

The lack of evidence for a TeV-mass graviton has been construed as constricting the Randall-Sundrum model. However, a doubly-warped generalization naturally avoids such restrictions. We develop, here, the formalism for extension of the Standard Model gauge bosons and fermions into such a six-dimensional bulk. Apart from ameliorating the usual problems such as flavour-changing neutral currents, this model admits two very distinct phases, with their own unique phenomenologies.
