F/W e+e- INTERACTIONS*

INTRODUCTION The field of e+e-interactions has provided a great deal of excitement in the past few years. 1-9 Primarily, interest has centered around the reaction +-ee-hadrons. This reaction is particularly attractive because we believe in electromagnetic perturbation theory, which implies that the cross section for hadron production is dominated by one photon annihilation of the electron and p...

On e + e − → W + W − → 4f(+γ) at LEP2 ∗

The results on ee → WW → 4f(+γ) obtained by different groups are compared with each other. Differences in the results for the total cross section of up to about 0.6 % are traced back to different ways of implementing the double-pole approximation.

Effects of TeV Scale Gravity on e+e− → W+W−

We study the process e+e− → W+W− to probe low-scale gravity at high energy linear colliders. A characteristic signature of extra-dimensions models is the forward-backward asymmetry due to the interference of spin2 graviton and spin-1 SM gauge boson exchange terms, even when rightpolarised electron beam is used. Our analysis shows that larger than 5% asymmetry is possible at a linear collider wi...

CP Violation in Heavy Neutrino Mediated e−e− →W−W−∗

We consider the reaction ee → WW mediated by possible heavy neutrino exchange at future LINAC energies of √ s >> 2mW . This reaction is sensitive to CP phases of the neutrino mixing matrices, even at the level of Born amplitudes. Certain integrated cross-sections are shown to have the power to resolve the CP phases when the experimental configurations are varied. Asymmetries sensitive to CP vio...
