Dynamics of D3-D7 Brane Inflation in Throats
Fang Chen, Hassan Firouzjahi
Dynamics of D3-branes in models of warped D3-D7 inflationary set up is studied where perturbative correction to the Kähler potential and the nonperturbative corrections to the…
On the Collision of Cosmic Superstrings
E. J. Copeland, H. Firouzjahi, T. W. B. Kibble +1
We study the formation of three-string junctions between (p,q)-cosmic superstrings, and collisions between such strings and show that kinematic constraints analogous to those found…
Lensing and CMB Anisotropies by Cosmic Strings at a Junction
Robert Brandenberger, Hassan Firouzjahi, Johanna Karouby
The metric around straight arbitrarily-oriented cosmic strings forming a stationary junction is obtained at the linearized level. It is shown that the geometry is flat. The sum rul…
Energy Radiation by Cosmic Superstrings in Brane Inflation
Hassan Firouzjahi
The dominant method of energy loss by a loop of cosmic D-strings in models of warped brane inflation is studied. It is shown that the energy loss via Ramond-Ramond field radiation…
Quest for a Self-Tuning Brane-World Solution to the Cosmological Constant Problem
James M. Cline, Hassan Firouzjahi
It has been proposed that the geometry of an extra dimension could automatically adjust itself to compensate for an arbitrary energy density on the 3-D brane which we are presumed…
Radion Mass is Milli-eV in the Goldberger-Wise Stabilization Mechanism
J. M. Cline, H. Firouzjahi
A complete calculation of the radion mass has been given by Tanaka and Montes, hep-th/0001092, and also by Csaki, Graesser and Kribs (in preparation), which both obtain the TeV-sca…
