## TL;DR

This paper investigates how a CP-violating two-Higgs-doublet model can simultaneously explain the muon g-2 anomaly and the electron EDM constraints, highlighting the model's parameter space limitations.

## Contribution

It provides a detailed analysis of the parameter space of the type-X 2HDM, demonstrating the constraints imposed by muon g-2 and electron EDM measurements on CP violation.

## Key findings

- CP-violating parameters are tightly constrained by muon g-2 and electron EDM data.
- The model can accommodate the muon g-2 anomaly within certain parameter regions.
- Significant enhancements in lepton magnetic and electric moments are possible through two-loop Barr-Zee diagrams.

## Abstract

The CP violating two-Higgs doublet model of type-X may enhance significantly the electric and magnetic moment of leptons through two-loop Barr-Zee diagrams. We analyze the general parameter space of the type-X 2HDM consistent with the muon $g-2$ and the electron EDM measurements to show how strongly the CP violating parameter is constrained in the region explaining the muon $ g-2$ anomaly.
