Highlights of Flavour Violation in the Presence of a 4th Generation

TL;DR

This paper reviews recent research on how adding a fourth generation of quarks and leptons affects flavour violation, rare decays, and CP violation, highlighting experimental constraints and implications for upcoming experiments.

Contribution

It provides an overview of the impact of a fourth generation on flavour violation and discusses the significance of epsilon-prime/epsilon constraints in this context.

Findings

Enhanced flavour violation signals with 4G

Constraints from epsilon-prime/epsilon are significant

Implications for LHC, SuperBelle, and NA62 experiments

Abstract

We present a short overview of recent work on the topic of flavour violation in the presence of a sequential fourth generation (4G) of quarks and leptons. We discuss the implications of this simple extension of the Standard Model (SM3) for rare decays and CP violating observables. The observables of interest were chosen with the start of the LHC, the approval of SuperBelle and the upcoming NA62 experiment in mind. A special emphasis is placed on the importance of epsilon-prime/epsilon as a constraint for this model.
