Hadronic light-by-light scattering contribution to the muon anomalous magnetic moment revisited
Kirill Melnikov, Arkady Vainshtein
We discuss hadronic light-by-light scattering contribution to the muon anomalous magnetic moment a_μ^{\rm lbl}, paying particular attention to the consistent matching between the s…
High-precision QCD at hadron colliders: electroweak gauge boson rapidity distributions at NNLO
Charalampos Anastasiou, Lance Dixon, Kirill Melnikov +1
We compute the rapidity distributions of W and Z bosons produced at the Tevatron and the LHC through next-to-next-to leading order in QCD. Our results demonstrate remarkable stabil…
A new method for real radiation at NNLO
C. Anastasiou, Kirill Melnikov, Frank Petriello
We propose a new method of computing real emission contributions to hard QCD processes. Our approach uses sector decomposition of the exclusive final-state phase space to enable ex…
Dilepton rapidity distribution in the Drell-Yan process at NNLO in QCD
Charalampos Anastasiou, Lance Dixon, Kirill Melnikov +1
We compute the rapidity distribution of the virtual photon produced in the Drell-Yan process through next-to-next-to-leading order in perturbative QCD. We introduce a powerful new…
The self-energy of improved staggered quarks
Thomas Becher, Kirill Melnikov
We calculate the fermion self-energy at O(alpha_s) for the Symanzik improved staggered fermion action used in recent lattice simulations by the MILC collaboration. We demonstrate t…
