  These lectures are a very brief introduction to low energy supersymmetry
(SUSY). The approach to the construction of SUSY Lagrangians based on the
superfield formalism is considered. The minimal supersymmetric standard model
(MSSM) is specified. The breakdown of gauge symmetry and Higgs phenomenology
within the simplest SUSY extensions of the standard model (SM) are briefly
reviewed. The upper bound on the mass of the lightest Higgs boson and little
hierarchy problem in SUSY models are discussed.
