Optimal observables for the measurement of three gauge boson couplings ine + e W + W

M Diehl, O Nachtmann - Zeitschrift für Physik C Particles and Fields, 1994 - Springer
We investigate the prospects of measuring anomalous couplings between gauge bosons at
electron-positron-colliders with optimal observables. Such observables are shown to contain …

Top-quark production in hadron-hadron collisions and anomalous top-quark–gluon couplings

P Haberl, O Nachtmann, A Wilch - Physical Review D, 1996 - APS
We discuss the influence of anomalous ttG couplings on total and differential tt production
cross sections in hadron-hadron collisions. We study in detail the effects of a chromoelectric …

-violating electric and weak dipole moments of the lepton from threshold to 500 GeV

W Bernreuther, O Nachtmann, P Overmann - Physical Review D, 1993 - APS
A number of CP-odd momentum correlations are investigated for τ pair production in e+ e−
collisions covering the energy range from threshold to 500 GeV. These correlations are in …

Quantum tomography with leptons at the FCC-ee: Entanglement, Bell inequality violation, , and anomalous couplings

M Fabbrichesi, L Marzola - Physical Review D, 2024 - APS
The Future Circular Collider (FCC)—in its first incarnation as a lepton collider—will produce,
according to the proposed design, more than 100 billion pairs of τ leptons after working for …

Physics of tau leptons

S Gentile, M Pohl - Physics reports, 1996 - Elsevier
We review the current status of τ physics from an experimental point of view. Results from all
experiments that have observed e+ e−→ τ+ τ−, from threshold to LEP energies, are …

The dehydrogenation of 2-butanol over copper-based catalysts: optimising catalyst composition and determining kinetic parameters

JN Keuler, L Lorenzen, S Miachon - Applied Catalysis A: General, 2001 - Elsevier
This work examines the dehydrogenation of 2-butanol over copper-based catalyst. The
effects of support type (MgO and SiO2) and copper loading on methyl ethyl ketone (MEK) …

Normal and transverse single tau polarization at the Z-peak

J Bernabéu, GA González-Sprinberg, J Vidal - Physics Letters B, 1994 - Elsevier
We study normal (to the collision plane) and transverse (within the collision plane) single-τ
polarization in τ pairs produced in e+ e− unpolarized collisions at the Z-resonance. The …

Search for CP violation in Z0τ + τ and an upper limit on the weak dipole moment of the τ lepton

OPAL collaboration - Zeitschrift für Physik C Particles and Fields, 1997 - Springer
An improved test of invariance in the reaction e+ e− τ+ τ− on the Z0 peak is performed using
the data sample recorded between 1991 and 1995 with the OPAL detector at LEP. Optimal …
