Title |
Effective field theory approach to classical and quantum gravity |
|
Abstract |
In this talk we will present an effective field theory approach to various problems in
gravitational physics. By
computing scattering amplitudes in quantum gravity we derive long-range classical and
quantum
contributions to the gravitational bound state of two bodies. We explain how modern amplitude
techniques
enable much simplified computations.
We describe how classical general gravity emerges from quantum loop.
Using an eikonal procedure we extract post-Newtonian general relativity correction as well as
long range
quantum corrections. We will explain why these quantum effects are universal to any
quantum gravity and
independent of the high-energy completion. |
