- The Many Ways to Galileon Inflation and an Intriguing Window in Parameter Space
- Time: 4:00 pm
- Place: 5280 Chamberlin
- Speaker: Matteo Fasiello, Case Western Reserve University
- Abstract: Galileon theories enjoy a number of properties that make their use in inflationary setups particularly compelling. We will illustrate how one arrives at a stable and predictive theory of Galileon inflation and characterize the predictions of this model. We further show how a region of the parameter space of the theory is consistent with a small bispectrum--large trispectrum configuration.
