Light dilatons in warped space: Higgs boson and LHCb anomalies

TL;DR

This paper explores a five-dimensional warped model with a light dilaton, examining its interactions with Standard Model particles, constraints from precision tests, potential to explain the Higgs-like resonance, and anomalies in B-meson decays.

Contribution

It introduces a novel warped space model featuring a light dilaton that can account for Higgs observations and B-meson decay anomalies.

Findings

Constraints on Kaluza-Klein mode masses from electroweak tests

Dilaton can mimic the Higgs boson in LHC data

Model explains B-meson decay anomalies

Abstract

We study the extension of the Standard Model (SM) with a light dilaton in a five dimensional warped model. In particular, we analyze the coupling of the dilaton with the SM matter fields, compare the model predictions with Electroweak Precisions Tests and find the corresponding bounds on the mass of the lightest Kaluza-Klein modes. We also investigate the possibility that the Higgs-like resonance found at the LHC can be a dilaton. Finally, we show that our set-up can also provide an explanation of the anomalies recently observed in $B$-meson decays.
