Ghosh, G. (2024, November 10). CP Violation and Flavour-Violating Di-Higgs Couplings in the Randall-Sundrum Model. arXiv. https://arxiv.org/abs/2411.06451v1
This research paper investigates the role of CP violation and flavor-violating di-Higgs couplings within the framework of the Randall-Sundrum (RS) model. The study aims to explore the phenomenological implications of these couplings, particularly their contributions to lepton flavor-violating decays and their potential for discovery at future colliders.
The authors employ a combination of theoretical calculations and Monte Carlo simulations to explore the parameter space of the RS model. They derive expressions for flavor-violating di-Higgs couplings and calculate their contributions to various lepton flavor-violating decays. Monte Carlo simulations are used to generate distributions of these couplings while considering experimental constraints on branching ratios for processes like τ → 3µ, τ → µγ, µ → eγ, and µ → 3e.
The RS model offers a viable framework for explaining both the hierarchy problem and the origin of CP violation and flavor violation. The study demonstrates that flavor-violating di-Higgs couplings in the RS model can lead to observable effects in LFV decays, providing a potential avenue for testing the model at future colliders.
This research contributes to the ongoing search for physics beyond the Standard Model by exploring the phenomenological implications of the RS model. The findings provide valuable insights into the interplay between flavor physics, CP violation, and extra-dimensional theories, guiding future experimental searches for new physics.
The study primarily focuses on lepton flavor-violating decays. Further research could explore the implications of flavor-violating di-Higgs couplings for quark flavor physics and CP violation in other sectors. Additionally, investigating the impact of higher-order corrections and exploring alternative extra-dimensional models could provide a more comprehensive understanding of flavor violation and CP violation beyond the Standard Model.
