Impact of recent $(g-2)_{\mu}$ measurement on the light CP-even Higgs scenario in general Next-to-Minimal Supersymmetric Standard Model

Understand

The General Next-to-Minimal Supersymmetric Standard Model (GNMSSM) is an attractive theory that is free from the tadpole problem and the domain-wall problem of $Z_3$-NMSSM, and can form an economic secluded dark matter (DM) sector to naturally predict the DM experimental results.

• It also provides mechanisms to easily and significantly weaken the constraints from the LHC search for supersymmetric particles.
• These characteristics enable the theory to explain the recently measured muon anomalous magnetic moment, $(g-2)_\mu$, in a broad parameter space that is consistent with all experimental results and at same time keeps the electroweak symmetry breaking natural.
• This work focuses on a popular scenario of the GNMSSM in which the next-to-lightest CP-even Higgs boson corresponds to the scalar discovered at the Large Hadron Collider (LHC).
