The Wilson Effective Kähler Potential For Supersymmetric Nonlinear Sigma Models
Renormalization group methods are used to determine the evolution of the low energy Wilson effective action for supersymmetric nonlinear sigma models in four dimensions. For the case of supersymmetric CP N −1 models, the Kähler potential is determined exactly and is shown to exhibit a non-trivial ultraviolet fixed point in addition to a trivial infrared fixed point. The strong coupling behavior...
متن کاملGeneralized complex geometry and supersymmetric non - linear sigma models
After an elementary presentation of the relation between supersymmetric nonlinear sigma models and geometry, I focus on 2D and the target space geometry allowed when there is an extra supersymmetry. This leads to a brief introduction to generalized complex geometry, a notion introduced recently by Hitchin which interpolates between complex and symplectic manifolds. Finally I present worldsheet ...
متن کاملGauged Supersymmetric Generalized Nonlinear Sigma Models for Quarks and Leptons*
We consider the idea of describing quarks and leptons, and their interactions, in terms of gauged supersymmetric generalized nonlinear sigma models. It is found that the best model is the one based on the Kahler manifold E7/sU(4) X U(1)4, with an atipropriate complex structure. The isotropy representation of the manifold is sufficient for embedding three families of quarks and leptons. We as10 ...
متن کاملThe Geometry of Supersymmetric D = 2 Nonlinear Sigma Models
This paper will consider supersymmetric nonlinear sigma models in two space-time dimensions. First, the rich variety of possible supersymmetries in two dimensions will be discussed. Next, a slight detour into some complex geometry will be taken to gather some useful definitions and results. Finally, it will be shown that requiring the sigma model to have extended supersymmetry imposes various g...
متن کاملGeneralized N=(2,2) Supersymmetric Non-linear Sigma Models
We rewrite the N = (2, 2) non-linear sigma model using auxiliary spinorial superfields defining the model on T ⊕∗ T , where T is the tangent bundle of the target space M. This is motivated by possible connections to Hitchin’s generalized complex structures. We find the general form of the second supersymmetry compatible with the known one for the original model. e-mail address: ulf.lindstrom@te...
