Brane Vacuum as Chain of Rotators
E. E. Donets, A. P. Isaev, C. Sochichiu +1
We analyse the noncommutative U(1) sigma model, which arises from the vacuum dynamics of the noncommutative charged tachyonic field. The sector of ``spherically symmetric'' excitat…
N=4 Superconformal Mechanics and the Potential Structure of AdS Spaces
E. E. Donets, A. Pashnev, V. O. Rivelles +2
The dynamics of an N=4 spinning particle in a curved background is described using the N=4 superfield formalism. The N=4 superconformal symmetr…
Auxiliary representations of Lie algebras and the BRST constructions
C. Burdik, A. Pashnev, M. Tsulaia
The method of construction of auxiliary representations for a given Lie algebra is discussed in the framework of the BRST approach. The corresponding BRST charge turns out to be no…
Partial supersymmetry breaking in Multidimensional N=4 SUSY QM
E. E. Donets, A. Pashnev, J. J. Rosales +1
The multidimensional N=4 supersymmetric quantum mechanics (SUSY QM) is constructed and the various possibilities for partial supersymmetry breaking are discussed. It is shown that…
