D-branes and constant electro-magnetic backgrounds
J. Bogaerts, A. Sevrin, J. Troost +2
We probe the effective worldvolume theory of a set of coinciding D-branes by switching on constant electro-magnetic fields on them. The comparison of the mass spectrum predicted by…

Properties of Semi-Chiral Superfields
J. Bogaerts, A. Sevrin, S. van der Loo +1
Whenever the N=(2,2) supersymmetry algebra of non-linear sigma-models in two dimensions does not close off-shell, a holomorphic two-form can be defined. The only known superfields…
