Four-Fermion Production in Electron-Positron Collisions
Martin W. Gruenewald, Giampiero Passarino, E. Accomando +37
This report summarises the results of the four-fermion working group of the LEP2-MC workshop, held at CERN from 1999 to 2000. Recent developments in the calculation of four-fermion…
An effective Lagrangian approach for unstable particles
W. Beenakker, F. A. Berends, A. P. Chapovsky
We propose a novel procedure for handling processes that involve unstable intermediate particles. By using gauge-invariant effective Lagrangians it is possible to perform a gauge-i…
Final-state radiation and line-shape distortion in resonance pair production
W. Beenakker, F. A. Berends, A. P. Chapovsky
In this letter it is shown how final-state QED corrections to the production of a pair of resonances can distort the line shape of such a resonance in a sizeable way. This effect d…
Meson--photon transition form factors and resonance cross-sections in e^+ e^- collisions
G. A. Schuler, F. A. Berends, R. van Gulik
Meson--photon--photon transition form factors for S-, P-, and D-wave states are calculated, the meson being treated as a non-relativistic heavy-quark--antiquark pair. The full depe…
Small-threshold behaviour of two-loop self-energy diagrams: some special cases
F. A. Berends, A. I. Davydychev, V. A. Smirnov
An algorithm to construct analytic approximations to two-loop diagrams describing their behaviour at small non-zero thresholds is discussed. For some special cases (involving two d…
Small-threshold behaviour of two-loop self-energy diagrams: two-particle thresholds
F. A. Berends, A. I. Davydychev, V. A. Smirnov
The behaviour of two-loop two-point diagrams at non-zero thresholds corresponding to two-particle cuts is analyzed. The masses involved in a cut and the external momentum are assum…
