Dual Identities inside the Gluon and the Graviton Scattering Amplitudes
S. -H. Henry Tye, Yang Zhang
Recently, Bern, Carrasco and Johansson conjectured dual identities inside the gluon tree scattering amplitudes. In this paper, we use the properties of the heterotic string and ope…
Duality Cascade in Brane Inflation
Rachel Bean, Xingang Chen, Girma Hailu +2
We show that brane inflation is very sensitive to tiny sharp features in extra dimensions, including those in the potential and in the warp factor. This can show up as observationa…
Particle Horizon and Warped Phenomenology
Horace Stoica, S. -H. Henry Tye, Ira Wasserman
Giant resonances of gravity Kaluza-Klein modes (with tensor couplings) in high energy collisions are expected in the Randall-Sundrum orbifold model that incorporates a plausible so…
Cosmology in the Randall-Sundrum Brane World Scenario
Horace Stoica, S. -H. Henry Tye, Ira Wasserman
The cosmology of the Randall-Sundrum scenario for a positive tension brane in a 5-D Universe with localized gravity has been studied extensively recently. Here we extend it to more…
