    KNEUR JL, Schildknecht D. ON ELECTROWEAK THEORIES WITH AN EXTRA SU(2)V VECTOR BOSON TRIPLET. NUCLEAR PHYSICS B. 1991;357(2-3):357-389.We examine an extended electroweak theory based on SU(2)L x SU(2)V x U(l)Y and constrained by rho = 1 at tree level. Various models previously considered in the literature appear as special cases of our framework. The non-decoupling of the additional neutral vector boson V0 for m(V) --> infinity is traced back to the extra point-like photon interaction of leptons and quarks contained in the Hung-Sakurai electroweak model based on gamma-W3 mixing. A comparison of the predictions of the present model with precision electroweak data (M(Z0), M(W +/-), sBAR(W)2) will allow one to quantify how firmly SU(2)L x U(1)Y symmetry of vector-boson-fermion interactions is established by these data

PHYSICS LETTERS B. 1991;262(1):93-101.One-loop corrected predictions following from the standard SU(2)L X U(1)Y theory, as well as predictions from an alternative which allows for local SU(2)L X U(1)Y violation, are confronted with the experimental data on the vector-boson masses and the electroweak mixing angle S(w)-2 (M(Z)2)

    BILENKY M, KNEUR JL, RENARD FM, Schildknecht D. STRONGLY COUPLED SU(2)NU BOSON AND LEP1 VERSUS LEP2. PHYSICS LETTERS B. 1993;316(2-3):345-354.If new strong interactions exist in the electroweak bosonic sector (e.g., strong Higgs sector, dynamical electroweak breaking, etc. ), it is natural to expect new resonances, with potentially strong couplings. We consider an additional vector-boson triplet, V+/-, V0, associated with an SU(2)V local symmetry under the specific (but rather natural) assumption that ordinary fermions are SU(2)v singlets. Mixing of the V triplet with the W+/- Z0 bosons effectively leads to an SU(2)L X U(1)Y violating vector-boson-fermion interaction which is strongly bounded by LEP1 data. In contrast, the potentially large deviation of the Z0W+W-coupling from its SU(2)L X U(1)Y value is hardly constrained by LEP1 data, Results from experiments with direct access to the trilinear Z0W+W- coupling (LEP200, NLC) are urgently needed
