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…
Double-vector multiplet and partially broken N=4, d=3 supersymmetry
E. Ivanov, S. Krivonos, O. Lechtenfeld
We elaborate on a new N=2, d=3 supermultiplet (double-vector multiplet) with a non-trivial off-shell realization of the central charge. Its bosonic sector comprises two abelian gau…
N=(4,4), 2D supergravity in SU(2)xSU(2) harmonic superspace
S. Bellucci, E. Ivanov
We work out the basics of conformal , 2D supergravity in the , 2D analytic harmonic superspace with two independent sets of harmonic variables. We define the rele…
Diverse PBGS Patterns and Superbranes
E. Ivanov
This is a brief account of the approach to superbranes based upon the concept of Partial Breaking of Global Supersymmetry (PBGS).
Quaternionic metrics from harmonic superspace : lagrangian approach and quotient construction
Evgeny Ivanov, Galliano Valent
Starting from the most general harmonic superspace action of self-interacting Q^+ hypermultiplets in the background of N=2 conformal supergravity, we derive the general action for…
