Planck 2018 and Brane Inflation Revisited
Renata Kallosh, Andrei Linde, Yusuke Yamada
We revisit phenomenological as well as string-theoretical aspects of D-brane inflation cosmological models. Phenomenologically these models stand out on par with -attractors, as…
Duality Constraints on Counterterms in Supergravities
Daniel Z. Freedman, Renata Kallosh, Yusuke Yamada
The UV finiteness found in calculations of the 4-point amplitude in supergravity at loop order has not been explained, which motivates our study of the rele…
U(1) symmetric -attractors
Yusuke Yamada
We present a class of supergravity -attractors with an approximate global U(1) symmetry corresponding to the axion direction. We also develop a multi-field generalization of the…
Supertrace formulae for nonlinearly realized supersymmetry
Divyanshu Murli, Yusuke Yamada
We derive the general supertrace formula for a system with chiral superfields and one nilpotent chiral superfield in global and local supersymmetry. The nilpotent multiplet is…
Hypernatural inflation
Andrei Linde, Dong-Gang Wang, Yvette Welling +2
We constructed a model of natural inflation in the context of -attractor supergravity, in which both the dilaton field and the axion field are light during inflation, and the in…
On quantum compatibility of counterterm deformations and duality symmetries in supergravities
Renata Kallosh, Hermann Nicolai, Radu Roiban +1
In supergravities there are hidden symmetries of equations of motion, described by duality groups respectively. UV divergence…
