Soft limits and color-kinematic dualities in perturbative quantum gravity
Abstract/Contents
- Abstract
- This thesis is a study of the perturbative behavior of quantum gravity through explicit tree- and loop-level supergravity calculations. First, I discuss how using universal soft limits could allow us to reconstruct tree-level amplitudes. Second, I obtain loop-level results in non-maximal (N < 8) supergravity using the double-copy prescription for generating gravity amplitudes from gauge-theory amplitudes, which follows from the recently discovered Bern-Carrasco-Johansson (BCJ) duality in gauge theory. I combine N = 0,1,2 super-Yang-Mills (sYM) amplitudes with N = 4 sYM amplitudes to obtain N = 4,5,6 supergravity amplitudes. I show how the double-copy prescription reproduces known one-loop amplitudes, which correspond to the first explicit demonstration of the validity of the double-copy prescription in non-maximal supergravity. I then present and discuss new amplitudes at two loops in N = 4,5,6 supergravity.
