Statistical Anisotropy from Vector Curvaton in D-brane Inflation
Konstantinos Dimopoulos, Danielle Wills, Ivonne Zavala
We investigate the possibility of embedding the vector curvaton paradigm in D-brane models of inflation in Type IIB string theory in a simple toy model. The vector curvaton is iden…
Revisiting Coupling Selection Rules in Heterotic Orbifold Models
Tatsuo Kobayashi, Susha L. Parameswaran, Saul Ramos-Sanchez +1
We study L-point couplings between twisted sector fields in heterotic orbifold compactifications, using conformal field theory. Selection rules provide an easy way to identify whic…
Nontrival Cosmological Constant in Brane Worlds with Unorthodox Lagrangians
Stefan Forste, Hans Peter Nilles, Ivonne Zavala
In self-tuning brane-world models with extra dimensions, large contributions to the cosmological constant are absorbed into the curvature of extra dimensions and consistent with fl…
