Implications of Higgs Sterility for the Higgs and Stop Sectors

Understand

The LHC data implies that the newly discovered Higgs boson h may be sterile (highly SM-like).

• In supersymmetric SMs (SSMs), Higgs couplings are often modified by Higgs mixing and stop loop corrections, so we study the Higgs sterility in the Higgs and stop sectors in two SSMs: (I) The Minimal SSM (MSSM).
• In the nearly decoupling region, the doublet-doublet mixing effect can only enhance C_{hb\bar b} by 2m_Z^2/M_A^2.
• Sterility places M_A\gtrsim 900 GeV.
