PHYSICS LETTERS B. 1991;263(2):291-297.Non-zero values of appropriately defined observables related to the spin-polarization (i.e. to the angular distribution of the decay products) of the W+ and the W- produced in e+e- annihilation constitute unambiguous signals for the presence of CP violation in the interactions responsible for the process e+e- --> W+W-

THE POTENTIAL OF A NEW LINEAR COLLIDER FOR THE MEASUREMENT OF THE TRILINEAR COUPLINGS AMONG THE ELECTROWEAK VECTOR BOSONS
No full textBILENKY M, KNEUR JL, RENARD FM, Schildknecht D. THE POTENTIAL OF A NEW LINEAR COLLIDER FOR THE MEASUREMENT OF THE TRILINEAR COUPLINGS AMONG THE ELECTROWEAK VECTOR BOSONS. NUCLEAR PHYSICS B. 1994;419(2):240-253.We study the accuracy to be obtained in measuring trilinear Z0W+W- and gammaW+W-couplings in the reaction e+e- --> W+W- at ''New Linear Collider'' (NLC) energies of 500 GeV to 1000 GeV. We derive simple scaling laws for the sensitivity in the measurement of these couplings. For most couplings the sensitivity increases as square-root L.s, where L denotes the integrated luminosity and square-root s denotes the e+e- center-of-mass energy. Detailed investigations based on various fits confirm these scaling laws and show that an accuracy of the order of the standard radiative corrections can be reached at the NLC for the design values of the luminosity
UNITARITY BOUNDS ON WW SCATTERING AND ELECTROWEAK TESTS AT LEP
No full textGOUNARIS G, RENARD FM, Schildknecht D. UNITARITY BOUNDS ON WW SCATTERING AND ELECTROWEAK TESTS AT LEP. Modern Physics Letters A. 1993;8(07):647-660.Replacing elementary Higgs exchange in vector-boson scattering by an angular-momentum-zero unitarity-saturating partial wave amplitude described by a dispersion relation which incorporates low-energy gauge theory and high-energy partial-wave unitarity constraints, we find an upper bound of LAMBDA less than or similar to LAMBDA(max) congruent-to 0.8 TeV for the scale, LAMBDA, at which saturation of partial wave unitarity is to occur. Upon inserting the partial wave amplitude into a novel integral representation for the bosonic vacuum polarization contribution to the electroweak rho parameter, DELTA(rhob), we establish an upper bound on -DELTA(rhob)(less than or similar to 0.033), while for the case of the elementary Higgs scalar, the integral representation reproduces the well known m(H)/m(W) formula for DELTA(rhob). The upper bound on -DELTA(rhob) implies that the value of the mass of the top quark extracted from LEP1 measurements becomes justified even in the case when the Higgs scalar is replaced by a strong-interaction-like J = 0 partial wave
