Supersymmetric Nonlinear Sigma - Models in 4 D , N = 1 Superspace
Using 4D, N = 1 superfield techniques, a discussion of the 6D sigmamodel possessing simple supersymmetry is given. Two such approaches are described. Foremost it is shown that the simplest and most transparent description arises by use of a doublet of chiral scalar superfields for each 6D hypermultiplet. A second description that is most directly related to projective superspace is also present...
متن کاملEguchi-Hanson Solitons
We present a new class of solutions in odd dimensions to Einstein’s equations containing either a positive or negative cosmological constant. These solutions resemble the even-dimensional Eguchi-Hanson(A)dS metrics, with the added feature of having Lorentzian signatures. They provide an affirmative answer to the open question as to whether or not there exist solutions with negative cosmological...
متن کاملQuasicomplex N = 2 , d = 1 Supersymmetric Sigma Models
We derive and discuss a new type of N = 2 supersymmetric quantum mechanical sigma models which appear when the superfield action of the (1,2,1) multiplets is modified by adding an imaginary antisymmetric tensor to the target space metric, thus completing the latter to a non-symmetric Hermitian metric. These models are not equivalent to the standard de Rham sigma models, but are related to them ...
متن کاملEguchi-Hanson Solitons in Odd Dimensions
We present a new class of solutions in odd dimensions to Einstein’s equations containing either a positive or negative cosmological constant. These solutions resemble the even-dimensional Eguchi-Hanson(A)dS metrics, with the added feature of having Lorentzian signatures. They are asymptotic to (A)dSd+1/Zp. In the AdS case their energy is negative relative to that of pure AdS. We present perturb...
متن کامل3-Branes on Eguchi-Hanson 6D Instantons
We use the approach used by Eguchi-Hanson in constructing four-dimensional instanton metrics and construct a class of regular six-dimensional instantons which are nothing but S × S resolved conifolds. We then also obtain D3-brane solutions on these EHresolved conifolds.
