Euclidean Supersymmetry, Twisting and Topological Sigma Models
C. M. Hull, U. Lindstrom, L. Melo dos Santos +2
We discuss two dimensional N-extended supersymmetry in Euclidean signature and its R-symmetry. For N=2, the R-symmetry is SO(2)\times SO(1,1), so that only an A-twist is possible.…

Topological Sigma Models with H-Flux
C. M. Hull, U. Lindstrom, L. Melo dos Santos +2
We investigate the topological theory obtained by twisting the N=(2,2) supersymmetric nonlinear sigma model with target a bihermitian space with torsion. For the special case in wh…
