Small cosmological signatures from multi-brane models
Carlo R. Contaldi, Gavin Nicholson, Horace Stoica
We analyse the signatures of brane inflation models with moduli stabilisation. These are hybrid inflation models with a non-trivial field-space metric which can induce complex traj…
Exciting gauge field and gravitons in a brane-anti-brane annihilation
A. Mazumdar, H. Stoica
In this paper we point out the inevitability of an explosive production of gauge field and gravity wave during an open string tachyon condensation in a cosmological setting. We wil…
Dynamics of F/D networks: the role of bound states
Mairi Sakellariadou, Horace Stoica
We study, via numerical experiments, the role of bound states in the evolution of cosmic superstring networks, being composed by p F-strings, q D-strings and (p,q) bound states. We…
Constraints on Brane Inflation and Cosmic Strings
Richard A. Battye, Bjorn Garbrecht, Adam Moss +1
By considering simple, but representative, models of brane inflation from a single brane-antibrane pair in the slow roll regime, we provide constraints on the parameters of the the…
Kaluza-Klein relics from warped reheating
Aaron Berndsen, James M. Cline, Horace Stoica
It has been suggested that after brane-antibrane inflation in a Klebanov-Strassler (KS) warped throat, metastable Kaluza-Klein (KK) excitations can be formed due to nearly-conserve…
Brane Decay and Defect Formation
Horace Stoica
Topological defects are generically expected to form in models of brane inflation. Brane-anti-brane annihilation provides a way to gracefully end inflation, and the dynamics of the…
