AdS pure spinor superstring in constant backgrounds
In this paper we study the pure spinor formulation of the superstring in
around point particle solutions of the classical equations of
motion. As a particular example we quantize the pure spinor string in the BMN
background.Comment: 17 pages. Typos corrected. References adde
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
