| Research Abstract |
The ATLAS and CMS collaborations at the LHC experiment reported hints of a standard model Higgs boson at about 125GeV, which can be naturally explained in a supersymmetric framework with supersymmetry breaking at 100-1000TeV. I studied its cosmological implications and proposed an inflation model based on U(1)B-L gauge symmetry. In this model the inflationary scale places an upper limit on the supersymmery breaking which explains the Higgs mass naturally.
