Maths HEP Lunchtime Seminars: Tests of Gravity, Three Ways

Presented by Tessa Baker, Oxford

14 March 2014 13:00 in CM221

Contrary to the situation that exists in the Solar System, the predictions of General Relativity (GR) have not yet been tested to high accuracy on cosmological scales. In order to implement such tests in an efficient and unbiased way, we need a sensible way of describing what non-GR gravity might look like.

This turns out to be a remarkably subtle task, with no obvious or unique answer. I'll describe several methods currently being pursued, ranging from the formal to the practical. I'll show how these approaches fit together, and can be used to build a machinery that translates the work of theorists into real-world numbers output by experiments.
