Di-photon production at the LHC
Zvi Bern, Lance Dixon, Carl Schmidt
The standard model production of two photons is one of the most important backgrounds to light Higgs boson production at the LHC. In this talk we discuss the di-photon background,…
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…
Strings and Supersymmetry as Tools for Perturbative QCD
L. Dixon
We review techniques simplifying the analytic calculation of one-loop QCD amplitudes with many external legs, for use in next-to-leading-order corrections to multi-jet processes. W…
New QCD Results from String Theory
Z. Bern, L. Dixon, D. A. Kosower
We discuss new results in QCD obtained with string-based methods. These methods were originally derived from superstring theory and are significantly more efficient than convention…
The Five Gluon Amplitude and One-Loop Integrals
Z. Bern, L. Dixon, D. A. Kosower
We review the conventional field theory description of the string motivated technique. This technique is applied to the one-loop five-gluon amplitude. To evaluate the amplitude a g…
