Brackets, Sigma Models and Integrability of Generalized Complex Structures
Sebastian Guttenberg
It is shown how derived brackets naturally arise in sigma-models via Poisson- or antibracket, generalizing a recent observation by Alekseev and Strobl. On the way to a precise form…
Boundary Terms in Supergravity and Supersymmetry
P. van Nieuwenhuizen, A. Rebhan, D. V. Vassilevich +1
We begin with the simplest possible introduction to supergravity. Then we discuss its spin 3/2 stress tensor; these results are new. Next, we discuss boundary conditions on fields…
A Vector Supersymmetry in Noncommutative U(1) Gauge Theory with the Slavnov Term
Daniel N. Blaschke, Francois Gieres, Olivier Piguet +1
We consider noncommutative U(1) gauge theory with the additional term, involving a scalar field lambda, introduced by Slavnov in order to cure the infrared problem. we show that th…
Quantum Mass and Central Charge of Supersymmetric Monopoles - Anomalies, current renormalization, and surface terms
Anton Rebhan, Peter van Nieuwenhuizen, Robert Wimmer
We calculate the one-loop quantum corrections to the mass and central charge of N=2 and N=4 supersymmetric monopoles in 3+1 dimensions. The corrections to the N=2 central charge ar…
