On Perturbative Gravity and Gauge Theory
Z. Bern, L. Dixon, D. C. Dunbar +3
We review some applications of tree-level (classical) relations between gravity and gauge theory that follow from string theory. Together with -dimensional unitarity, these rela…
Perturbative Relations between Gravity and Gauge Theory
Z. Bern, L. Dixon, D. C. Dunbar +2
We review the relations that have been found between multi-loop scattering amplitudes in gauge theory and gravity, and their implications for ultraviolet divergences in supergravit…
Multi-Leg One-Loop Gravity Amplitudes from Gauge Theory
Z. Bern, L. Dixon, M. Perelstein +1
By exploiting relations between gravity and gauge theories, we present two infinite sequences of one-loop n-graviton scattering amplitudes: the `maximally helicity-violating' ampli…
Perturbative Relationships Between QCD and Gravity and Some Implications
Z. Bern, L. Dixon, D. C. Dunbar +2
We discuss nontrivial examples illustrating that perturbative gravity is in some sense the `square' of gauge theory. This statement can be made precise at tree-level using the Kawa…
One-Loop n-Point Helicity Amplitudes in (Self-Dual) Gravity
Z. Bern, L. Dixon, M. Perelstein +1
We present an ansatz for all one-loop amplitudes in pure Einstein gravity for which the n external gravitons have the same outgoing helicity. These loop amplitudes, which are ratio…
On the Relationship between Yang-Mills Theory and Gravity and its Implication for Ultraviolet Divergences
Z. Bern, L. Dixon, D. C. Dunbar +2
String theory implies that field theories containing gravity are in a certain sense `products' of gauge theories. We make this product structure explicit up to two loops for the re…
