Proliferation of sharp kinks on cosmic (super-)string loops with junctions
P. Binetruy, A. Bohe, T. Hertog +1
Motivated by their effect on the gravitational wave signal emitted by cosmic strings, we study the dynamics of kinks on strings of different tensions meeting at junctions. The prop…
Gravitational Wave Bursts from Cosmic Superstrings with Y-junctions
P. Binetruy, A. Bohe, T. Hertog +1
Cosmic superstring loops generically contain strings of different tensions that meet at Y-junctions. These loops evolve non-periodically in time, and have cusps and kinks that inte…
Dynamical solution of supergravity
Pierre Binetruy, Misao Sasaki, Kunihito Uzawa
We present a class of dynamical solutions for an intersecting D4-D8 brane system in ten-dimensional type IIA supergravity. The dynamical solutions reduces to a static warped AdS_6…
Dynamical D4-D8 and D3-D7 branes in supergravity
Pierre Binetruy, Misao Sasaki, Kunihito Uzawa
We present a class of dynamical solutions for intersecting D4-D8 and D3-D7 brane systems in ten-dimensional type IIA and IIB supergravity. We discuss if these solutions can be reco…
Twenty-five Questions for String Theorists
Pierre Binetruy, G. L. Kane, Joseph Lykken +1
In an effort to promote communication between the formal and phenomenological branches of the high-energy theory community, we provide a description of some important issues in sup…
Local Axion Cosmic Strings from Superstrings
Stephen C. Davis, Pierre Binetruy, Anne-Christine Davis
Axionic cosmic string solutions are investigated in a superstring motivated model with a pseudo-anomalous U(1) gauge symmetry. The inclusion of a gauge field and spatially varying…
