One-Loop Gluonic Amplitudes from Single Unitarity Cuts
E. W. Nigel Glover, Ciaran Williams
We show that one-loop amplitudes in massless gauge theories can be determined from single cuts. By cutting a single propagator and putting it on-shell, the integrand of an n-point…
One-loop phi-MHV amplitudes using the unitarity bootstrap: the general helicity case
E. W. N. Glover, Pierpaolo Mastrolia, Ciaran Williams
We consider a Higgs boson coupled to gluons via the five-dimensional effective operator H tr G_{μν}G^{μν}. We treat H as the real part of a complex field phi that couples to the se…
Jet rates in electron-positron annihilation at O(α_s^3) in QCD
A. Gehrmann-De Ridder, T. Gehrmann, E. W. N. Glover +1
We compute production rates for two, three, four and five jets in electron-positron annihilation at the third order in the QCD coupling constant. At this order, three-jet productio…
Event shapes in annhilation at NNLO
A. Gehrmann-De Ridder, T. Gehrmann, E. W. N. Glover +1
We report first results on the calculation of NNLO corrections to event shape distributions in electron-positron annhilation. The corrections are sizeable for all variables, howeve…
