Inflating with Baryons
Daniel Baumann, Daniel Green
We present a field theory solution to the eta problem. By making the inflaton field the phase of a baryon of SU(N_c) supersymmetric Yang-Mills theory we show that all operators tha…
Direct Gaugino Mediation
Daniel Green, Andrey Katz, Zohar Komargodski
We describe renormalizable supersymmetric four-dimensional theories which lead to gaugino mediation and various generalizations thereof. Even though these models are strongly coupl…
Exactly Marginal Deformations and Global Symmetries
Daniel Green, Zohar Komargodski, Nathan Seiberg +2
We study the problem of finding exactly marginal deformations of N=1 superconformal field theories in four dimensions. We find that the only way a marginal chiral operator can beco…
Desensitizing Inflation from the Planck Scale
Daniel Baumann, Daniel Green
A new mechanism to control Planck-scale corrections to the inflationary eta parameter is proposed. A common approach to the eta problem is to impose a shift symmetry on the inflato…
