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…
Recursive actions for scalar theories
C. Dams, R. Kleiss, P. Draggiotis +3
We introduce a class of self-interacting scalar theories in which the various coupling contants obey a recursive relation. These imply a particularly simple form for the generating…
WW Cross-sections and Distributions
W. Beenakker, F. A. Berends, E. N. Argyres +20
We present the results obtained by the "WW Cross-sections and Distributions" working group during the CERN Workshop "Physics at LEP2" (1994/1995)
Stable Calculations for Unstable Particles: Restoring Gauge Invariance
Ernestos N. Argyres, Wim Beenakker, Ansgar Denner +6
We discuss theoretical and phenomenological aspects of the use of boson propagators with energy-dependent widths in predictions for high-energy scattering processes. In general, ga…
Nullification of multi-Higgs threshold amplitudes in the Standard Model
E. N. Argyres, R. Kleiss, C. G. Papadopoulos
We show that nullification of all tree-order threshold amplitudes involving Higgs particles in the Standard Model occurs, provided that certain equations relating the masses of all…
Multiscalar amplitudes to all orders in perturbation theory
E. N. Argyres, Ronald H. P. Kleiss, Costas G. Papadopoulos
A method for calculating loop amplitudes at the multiboson threshold is presented, based on Feynman-diagram techniques. We explicitly calculate the one-loop amplitudes in both $ϕ^4…
