Query: Supersymmetry breaking in the three-dimensional nonlinear sigma model   In this work we discuss the phase structure of a deformed supersymmetric
nonlinear sigma model in a three-dimensional space-time. The deformation is
introduced by a term that breaks supersymmetry explicitly, through imposing a
slightly different constraint to the fundamental superfields of the model.
Using the tadpole method, we compute the effective potential at leading order
in 1/N expansion. From the gap equations, i.e., conditions that minimize the
effective potential, we observe that this model presents two phases as the
ordinary model, with two remarkable differences: 1) the fundamental fermionic
field becomes massive in both phases of the model, which is closely related to
the supersymmetry breaking term; 2) the O(N) symmetric phase presents a
meta-stable vacuum.
