# Supersymmetric D-term Twin Higgs

## TL;DR

This paper introduces a supersymmetric Twin Higgs model utilizing a D-term potential from a new U(1) gauge symmetry, achieving realistic Higgs mass and low electroweak tuning with relatively light stops.

## Contribution

It presents a novel supersymmetric Twin Higgs framework with a D-term quartic, enabling lighter stops and reduced tuning compared to previous models.

## Key findings

- Higgs mass of 125 GeV achieved with stop masses below 1 TeV.
- Electroweak tuning as low as 20% is possible.
- Stop masses around 2 TeV with about 10% tuning are feasible.

## Abstract

We propose a new type of supersymmetric Twin Higgs model where the SU(4) invariant quartic term is provided by a D-term potential of a new U(1) gauge symmetry. In the model the 125 GeV Higgs mass can be obtained for stop masses below 1 TeV, and a tuning required to obtain the correct electroweak scale can be as low as 20 %. A stop mass of about 2 TeV is also possible with tuning of order O(10) %.
