Further numerical results on non-factorizable corrections to fermions

Further numerical results on non-factorizable corrections to e + e − → 4 fermions

Numerical results on non-factorizable corrections to ee → WW → 4 fermions with semi-leptonic and hadronic final states, as well as to ee → ZZ → 4 fermions, are presented. The corrections turn out to be small in comparison to the experimental uncertainty of LEP2, but they might compete with the expected accuracy at future ee-colliders.

Non - factorizable photonic corrections to e + e − → WW → 4 fermions

Abstract: We study the non-factorizable corrections to W-pair-mediated four-fermion production in e+e− annihilation in double-pole approximation. We show how these corrections can be combined with the known corrections to the production and the decay of on-shell W-boson pairs, and how the full off-shell Coulomb singularity is included. Moreover, we find that the actual form of the real non-fact...

Further Results on Betweenness Centrality of Graphs

Betweenness centrality is a distance-based invariant of graphs. In this paper, we use lexicographic product to compute betweenness centrality of some important classes of graphs. Finally, we pose some open problems related to this topic.

Non-factorizable photonic corrections to resonant production and decay of many unstable particles

Electroweak radiative corrections to the production of high-multiplicity final states with several intermediate resonances in most cases can be sufficiently well described by the leading contribution of an expansion about the resonance poles. In this approach, also known as pole approximation, corrections are classified into separately gauge-invariant factorizable and non-factorizable correctio...
