Analytic one-loop amplitudes for a Higgs boson plus four partons
Lance J. Dixon, Yorgos Sofianatos
We compute the one-loop QCD amplitudes for the processes HqqQQ and Hqqgg, the latter restricted to the case of opposite-helicity gluons. Analytic expressions are presented for the…
Matter Dependence of the Three-Loop Soft Anomalous Dimension Matrix
Lance J. Dixon
The resummation of soft gluon exchange for QCD hard scattering requires a matrix of anomalous dimensions, which has been computed through two loops. The two-loop matrix is proporti…
Is N = 8 Supergravity Ultraviolet Finite?
Zvi Bern, Lance J. Dixon, Radu Roiban
Conventional wisdom holds that no four-dimensional gravity field theory can be ultraviolet finite. This understanding is based mainly on power counting. Recent studies confirm that…
Counterterms in Supergravity
Z. Bern, D. Dunbar, L. Dixon +5
We examine the ultraviolet behaviour of supergravity theories as a function of dimension and number of supercharges. We do so by the computation of one and two-loop physical on-she…
