# Exotic Leptonic solutions to observed anomalies in lepton universality observables and more

## TL;DR

This paper explores exotic leptonic models introducing new scalars and leptons to explain anomalies in lepton universality, muon g-2, baryogenesis, dark matter, and neutrino masses, predicting unique collider signatures for future experiments.

## Contribution

It proposes novel exotic leptonic solutions that unify explanations for multiple anomalies and predicts distinctive collider signatures for upcoming high-energy physics experiments.

## Key findings

- Models explain lepton universality violations and muon g-2
- Predicted signatures include heavy stable charged particles and vector-like leptons
- Potential for detection in HL-LHC, ILC, and CEPC experiments

## Abstract

In this talk I will present the work that we did in \cite{1}\cite{2}\cite{3}\cite{4}\cite{5} related to observed lepton universality violation by Babar, Belle and LHCb in R($D^{(*)}$) and $R_{K^{(*)}}$ as well as the reported deviation in muon (g-2) by BNL. We had shown that all these anomalies as well as Baryon-genesis, Dark-matter and small neutrino masses could be explained by introducing new exotic scalars, leptons and scalar-leptoquarks only. It turn out that some of these models have very peculiar signatures such as prediction of existence of heavy stable charged particle \cite{1}\cite{2}, vector like fourth generation leptons \cite{3} or even scalar Baryonic DM candidates etc. Some of these models turn out to have very unique collider signatures such as $ee/pp \rightarrow \mu\mu(\tau\tau)\ +\ missing\ energy\ (ME)$, see \cite{1}\cite{2}\cite{4}. This is interesting in the sense that such peculiar signatures of these new particles can be searched in the upcoming HL-LHC or with even better chance of observing these signatures are in the upcoming precision machines such as ILC, CEPC etc.
