Soft supersymmetry breaking in the nonlinear sigma model
In this work we discuss the dynamical generation of mass in a deformed supersymmetric nonlinear sigma model in a two-dimensional ()
space-time. We introduce the deformation by imposing a constraint that softly
breaks supersymmetry. Through the tadpole method, we compute the effective
potential at leading order in expansion showing that the model exhibit a
dynamical generation of mass to the matter fields. Supersymmetry is recovered
in the limit of the deformation parameter going to zero.Comment: 9 pages, 2 figures. Revised version. arXiv admin note: text overlap
