On the decoupling of heavy modes in Kaluza-Klein theories
In this paper we examine the 4-dimensional effective theory for the light Kaluza-Klein (KK) modes. Our main interest is in the interaction terms. We point out that the contribution of the heavy KK modes is generally needed in order to reproduce the correct ...
2006Brane nucleation as decay of the tachyon false vacuum
It is well known that spherical D-branes are nucleated in the presence of an external RR electric field. Using the description of D-branes as solitons of the tachyon field on non-BPS D-branes, we show that the brane nucleation process can be seen as the de ...
American Physical Soc2005Brane to brane gravity mediation of supersymmetry breaking
Riccardo Rattazzi, Claudio Scrucca
We extend the results of Mirabelli and Peskin to supergravity. We study the compactification on S-1/Z(2) of Zucker's off-shell formulation of 5D supergravity and its coupling to matter at the fixed points. We clarify some issues related to the off-shell de ...
2003Nonlocal symmetry breaking in Kaluza-Klein theories
Scherk-Schwarz gauge symmetry breaking of a D-dimensional field theory model compactified on a circle is analyzed. It is explicitly shown that forbidden couplings in the,unbroken theory appear in the one-loop effective action only in a nonlocal way, implyi ...
2001On the effective action of stable non-BPS branes
We study the world-volume effective action of stable non-BPS branes present in Type II theories compactified on K3. In particular, by exploiting the conformal description of these objects available in the orbifold limit, we argue that their world-volume ef ...
2000Black hole-D-brane correspondence: An example
We explore the connection between D-branes and black holes in one particular case: a D3-brane compactified to four dimensions on T-6/Z(3). Using the D-brane boundary state description, we show the equivalence with a double extremal N = 2 black hole solutio ...
Springer Verlag1999A note on supersymmetric D-brane dynamics
We study the spin dependence of D-brane dynamics in the Green-Schwarz formalism of boundary states. In particular we show how to interpret insertion of supercharges on the boundary state as sources of non-universal spin effects in D-brane potentials. In th ...
