Phenomenological features in a model with non-universal gaugino CP phases

TL;DR

This paper explores a supersymmetry model with non-universal gaugino CP phases, demonstrating it can align with experimental EDM constraints and predict superpartner masses around 100 GeV, while analyzing Higgs sector compatibility.

Contribution

It introduces a SUSY breaking model with non-universal gaugino masses and CP phases that remain consistent with EDM constraints and allows for lighter superpartners.

Findings

Large CP phases are compatible with EDM constraints.

Superpartner masses can be around 100 GeV.

Higgs sector remains consistent with experimental data.

Abstract

We study phenomenological features in an extended gauge mediation SUSY breaking model which has non-universal gaugino masses and CP phases. We show that large CP phases in soft SUSY breaking parameters can be consistent with the constraints coming from the electric dipole moment (EDM) of an electron, a neutron, and also a mercury atom. Masses of the superpartners are not necessarily required to be larger than 1 TeV but allowed to be O(100) GeV. We also investigate the mass spectrum of Higgs scalars and their couplings to gauge bosons in that case. Compatibility of this model with the present experimental data on the Higgs sector is discussed.
