I am grateful to Enrico Pajer for taking my as a summer student and to the CMS for providing partial funding.
Our aim is to derive cosmological correlators/amplitudes in a systemic way. Such theoretical computations for inflation can be used as a test for (perturbative) quantum gravity.
The group is working on this and in the future I may post updates/links to papers. But for now:
- My talk at the Summer Research Festival about my work, including a novel result.
- A paper by my supervisor (very related to the topics we have been look into), were my contributions are acknowledged: Building a Boostless Bootstrap for the Bispectrum, arXiv:2010.12818 [hep-th]
- A set of notes I wrote during the readig part of the project. They cover the material needed to compute primordial inflationary correlators. Three and four points correlators for P(X,φ) inflationary Lagrangians are computed. The calculations needed to obtain the results of Maldacena’s paper on primordial non-gaussianity are reproduced. It also explains the spinor-helicity formalism for scattering amplitudes in QFT:
