D3-branes dynamics and black holes
M. Bertolini, P. Fre`, R. Iengo +1
Using the D3-brane as the fundamental tool, we adress two aspects of D-branes physics. The first regards the interaction between two electromagnetic dual D-branes in 10 dimensions.…
Black hole - D-brane correspondence: An example
M. Bertolini, P. Fre, F. Hussain +3
We explore the connection between D-branes and black holes in one particular case: a -brane compactified to four dimensions on . Using the -brane boundary state des…
About the Matrix model computation of three-graviton scattering
Marco Fabbrichesi, Gabriele Ferretti, Roberto Iengo
It is briefly explained why recent claims about the vanishing of the one-loop effective potential in Matrix theory, thus invalidating the possible agreement with supergravity, do n…
Pair Production of Open Strings - Relativistic versus Dissipative Dynamics
C. S. Acatrinei, R. Iengo
We study the pair production of open strings in constant electric fields, using a general framework which encodes both relativistic string theory and generic linearly extended syst…
Supergravity and matrix theory do not disagree on multi-graviton scattering
Marco Fabbrichesi, Gabriele Ferretti, Roberto Iengo
We compare the amplitudes for the long-distance scattering of three gravitons in eleven dimensional supergravity and matrix theory at finite N. We show that the leading supergravit…
Black holes as D3-branes on Calabi-Yau threefolds
Matteo Bertolini, Pietro Fre`, Roberto Iengo +1
We show how an extremal Reissner-Nordstrom black hole can be obtained by wrapping a dyonic D3-brane on a Calabi-Yau manifold. In the orbifold limit T^6/Z_3, we explicitly show the…
