From Amplitudes to Cosmology

Regular Seminar Arthur Lipstein (Durham)

room G. O. Jones 610
abstract:

Whereas scattering amplitudes probe physics at the shortest distances, cosmology probes physics at the largest scales. Nevertheless, many concepts discovered in the study of scattering amplitudes have an analogue for cosmological observables. In this talk I will describe some aspects of this program which I have recently been investigating such as the double copy, scattering equations, and soft limits, and will discuss how these directions are interrelated.
