| description | Searches for new particles beyond the Standard Model (SM) are an important task for the Large Hadron Collider (LHC). In this paper, we investigate the properties of the heavy non-SM Higgs bosons in the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi>μ</mi></semantics></math></inline-formula>-term extended Next-to-Minimal Supersymmetric Standard Model (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi>μ</mi></semantics></math></inline-formula>NMSSM). We scan the parameter space of the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi>μ</mi></semantics></math></inline-formula>NMSSM considering the basic constraints from Higgs data, dark matter (DM) relic density, and LHC searches for sparticles.

Then, we discuss the exotic decay modes of heavy Higgs bosons decaying into SM-like Higgs bosons.
