Partial spontaneous breaking of two-dimensional supersymmetry
E. Ivanov, S. Krivonos, O. Lechtenfeld +1
We construct low-energy Goldstone superfield actions describing various patterns of the partial spontaneous breakdown of two-dimensional N=(1,1), N=(2,0) and N=(2,2) supersymmetrie…
On the Integrability of Covariant Field Theory for Open N=2 Strings
Olaf Lechtenfeld, Alexander D. Popov
We discuss the integrability of the Berkovits-Siegel open string field equations and derive an infinite set of their non-local (solution-generating) symmetries. The string field eq…
Null Vectors in Logarithmic Conformal Field Theory
Michael A. I. Flohr
The representation theory of the Virasoro algebra in the case of a logarithmic conformal field theory is considered. Here, indecomposable representations have to be taken into acco…
Actions and symmetries of NSR superstrings and D-strings
Friedemann Brandt, Alexander Kling, Maximilian Kreuzer
We present all NSR superstring and super-D-string actions invariant under a set of prescribed gauge transformations, and characterize completely their global symmetries. In particu…
Hidden Symmetries of the Open N=2 String
Tatiana A. Ivanova, Olaf Lechtenfeld
It is known for ten years that self-dual Yang-Mills theory is the effective field theory of the open N=2 string in 2+2 dimensional spacetime. We uncover an infinite set of abelian…
N=2 Quantum String Scattering
Gordon Chalmers, Olaf Lechtenfeld, Bernd Niemeyer
We calculate the genus-one three- and four-point amplitudes in the 2+2 dimensional closed N=(2,2) worldsheet supersymmetric string within the RNS formulation. Vertex operators are…
