ELectroweak naturalness requires a SUSY mu parameter ~100-200 GeV

A small mu parameter can be easily generated from large m_3/2 via

Higgs Theory and Experiment

The presence of extra scalar singlets is a feature of several motivated extensions of the Standard Model, and the mixing of such a singlet with the Higgs boson is allowed to be quite large by current experiments. I will consider both direct and indirect searches, and quantify the current constraints as well as the prospects for future hadron and lepton machines. The results are first presented...

We explore the implications of a new minimal supersymmetric hybrid inflation model in which the MSSM µ term arises from a coupling of the Higgs doublets to the inflaton sector, with |µ| required to be greater than the gravitino mass m_G. Successful inflation with the scalar spectral index ns = 0.96−0.97, is followed by a relatively high reheat temperature, T_RH ≳ 10^12 GeV, in the presence of...

The MSSM leads to precise predictions of the properties of the light Higgs boson degrees of freedom that depend on only a few relevant supersymmetry breaking parameters. There is an upper bound on the mass of the lightest neutral Higgs boson, which for a supersymmetric spectrum of the order of a TeV, is barely above the measured M_h = 125 GeV at the LHC. Raising this bound by considering a...
