A subtraction scheme for NNLO computations
Radja Boughezal, Kirill Melnikov, Frank Petriello
We use the known soft and collinear limits of tree- and one-loop scattering amplitudes -- computed over a decade ago -- to explicitly construct a subtraction scheme for next-to-nex…
The four-dimensional helicity scheme and dimensional reconstruction
Radja Boughezal, Kirill Melnikov, Frank Petriello
The four-dimensional helicity regularization scheme is often used in one-loop QCD computations. It was recently argued in Ref. [1] that this scheme is inconsistent beyond the one-l…
Hadronic light-by-light scattering contribution to the muon magnetic anomaly: constituent quark loops and QCD effects
Radja Boughezal, Kirill Melnikov
The hadronic light-by-light scattering contribution to the muon anomalous magnetic moment can be estimated by computing constituent quark loops. Such an estimate is very sensitive…
Constraints on heavy colored scalars from Tevatron's Higgs exclusion limit
Radja Boughezal
The null search for the Higgs boson at the Tevatron implies strong constraints on heavy colored particles that increase the gluon-fusion induced production rate of the Higgs. We in…
Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables
LHC Higgs Cross Section Working Group, S. Dittmaier, C. Mariotti +62
This Report summarizes the results of the first 10 months' activities of the LHC Higgs Cross Sections Working Group. The main goal of the working group was to present the status-of…
