Curvature and isocurvature perturbations in two-field inflation
Z. Lalak, D. Langlois, S. Pokorski +1
We study cosmological perturbations in two-field inflation, allowing for non-standard kinetic terms. We calculate analytically the spectra of curvature and isocurvature modes at Hu…
The Price of WMAP Inflation in Supergravity
J. Ellis, Z. Lalak, S. Pokorski +1
The three-year data from WMAP are in stunning agreement with the simplest possible quadratic potential for chaotic inflation, as well as with new or symmetry-breaking inflation. We…
Stability of flux compactifications and the pattern of supersymmetry breaking
K. Choi, A. Falkowski, H. P. Nilles +2
We extend the KKLT approach to moduli stabilization by including the dilaton and the complex structure moduli into the effective supergravity theory. Decoupling of the dilaton is n…
Deconstructed U(1) and Supersymmetry Breaking
Emilian Dudas, Adam Falkowski, Stefan Pokorski
We discuss supersymmetry breaking induced by simultaneous presence of a Wilson-line type superpotential and boundary-localized Fayet-Iliopoulos terms in a four dimensional theory b…
