Аннотация:Consistent and phenomenologically successful scenarios of the Minimal Supersymmetric
Standard Model (MSSM) include the Higgs potential which is positively
defined at large fields and has two minima, one of them is true and stable vacuum in
which we live. However, the effective terms of the MSSM potential which appear at
a loop level can spoil the vacuum stability leading to a metastable or unstable vacuum
configurations. Such a situation is analysed and the general necessary conditions of vacuum
stability in the MSSM parameter space are imposed. For a majority of the MSSM
"benchmark scenarios" which are used for reconstruction of production channels at the
LHC, the effective potential is found to be always stable, except light stop and τ-phobic
scenarios.
