Diagrammatic proof of the BCFW recursion relation for gluon amplitudes in QCD
Petros D. Draggiotis, Ronald H. P. Kleiss, Achilleas Lazopoulos +1
We present a proof of the Britto-Cachazo-Feng-Witten tree-level recursion relation for gluon amplitudes in QCD, based on a direct equivalence between BCFW decompositions and Feynma…
Non-Concave Bare Actions with Concave Effective Actions I: Zero Dimensions
E. N. Argyres, M. T. M. van Kessel, R. H. P. Kleiss
We perform an explicit computation of the effective action for a few zero-dimensional Euclidean field theories in which the bare action exhibits several (or infinitely many) minima…
Error in Monte Carlo, quasi-error in Quasi-Monte Carlo
R. H. Kleiss, A. Lazopoulos
While the Quasi-Monte Carlo method of numerical integration achieves smaller integration error than standard Monte Carlo, its use in particle physics phenomenology has been hindere…
Renormalization-Scheme-Independent Perturbation Theory by Resumming Logarithms
Chris Dams, Ronald Kleiss
Results of perturbation theory in quantum field theory generally depend on the renormalization scheme that is in use. In particular, they depend on the scale. We try to make pertur…
