Non-BPS Dirichlet branes
Oren Bergman, Matthias R Gaberdiel
A brief introduction to the boundary state approach to Dirichlet branes is given. The example of the non-BPS D-string of Type IIA on K3 is analysed in some detail, and its dual het…
Branes and Supersymmetry Breaking in Three Dimensional Gauge Theories
Oren Bergman, Amihay Hanany, Andreas Karch +1
It is shown that supersymmetry is spontaneously broken in certain three-dimensional supersymmetric gauge theories, by using the s-rule in their string theory realization as brane c…
Dualities of Type 0 Strings
O. Bergman, M. R. Gaberdiel
It is conjectured that the two closed bosonic string theories, Type 0A and Type 0B, correspond to certain supersymmetry breaking orbifold compactifications of M-theory. Various imp…
Non-BPS States in Heterotic - Type IIA Duality
O. Bergman, M. R. Gaberdiel
The relation between some perturbative non-BPS states of the heterotic theory on T^4 and non-perturbative non-BPS states of the orbifold limit of type IIA on K3 is exhibited. The r…
Brane Transfer Operations and T-Duality of Non-BPS States
Oren Bergman, Eric G. Gimon, Petr Horava
Using the relation between D-brane charges and K-theory, we study non-BPS D-branes and their behavior under T-duality. We point out that in general compactifications, D-brane charg…
