Quantum Extremism: Effective Potential and Extremal Paths
E. N. Argyres, M. T. M. van Kessel, R. H. P. Kleiss
The reality and convexity of the effective potential in quantum field theories has been studied extensively in the context of Euclidean space-time. It has been shown that canonical…
The Path-Integral Approach to the N=2 Linear Sigma Model
E. N. Argyres, M. T. M. van Kessel, R. H. P. Kleiss
In QFT the effective potential is an important tool to study symmetry breaking phenomena. It is known that, in some theories, the canonical approach and the path-integral approach…
Path Integrals in Polar Field Variables in QFT
E. N. Argyres, C. G. Papadopoulos, R. H. P. Kleiss +1
We show how to transform a -dimensional Euclidean path integral in terms of two (Cartesian) fields to a path integral in terms of polar field variables. First we present a conje…
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)
