Inflation: Generic predictions and nilpotent superfields Dries Coone, April 2018
1. The Hubble parametrization for inflation is cleaner than the potential parametrization, but the potential parametrization is more convenient for particle physics. [Chapters 3 & 4]
2. The Horizon flow code fails in generating generic predictions of inflation, since these predictions are model dependent (i.e. the generic predictions depend on the shape of the potential). However, it is possible to
investigate which potential shapes generically resemble the current observational data best. [Chapters 4 & 5]
3. By considering a strong coupling between the inflaton and the Ricci scalar, many inflation models can be made consistent with the data from the Planck satellite. [Chapter 6]
4. To obtain precise predictions of the early universe, it is required that the reheating era is better understood. [Chapters 7 & 8]
5. It is possible to construct large-field inflation models based on the nilpotent framework in which supersymmetry breaking is mediated to the standard model through gauge mediation. In addition, it is possible to make predictions for such a model concerning both the early universe and the standard model of particle physics. [Chapter 8]
6. Computers are perfect for solving problems, but it is not always clear what the problem is they answer.
7. The advantage of going abroad is that one can complain about everything.
8. To learn to play a musical instrument and to learn to do physics require the same skills. In order of importance: dedication, practice and talent.
