ASYMMETRIC LEFT-RIGHT MODEL OF ELECTROWEAK INTERACTIONS

The asymmetric left-right model (LRM) is considered. The differential and the total cross sections of the reaction e-e+ --> W-W+ are calculated at the level of the improved Born approximation. The investigation of the unpolarized e-e+ beams shows that already at the CERN e+e- collider LEP II energies we can either establish or limit such parameters of the LRM as DELTArho(M) and PHI. It is demonstrated that the LRM manifestations are maximum for e(R)-e(L)+ beams. The measurements of the sigma(eR-eL+) --> W-W+ will yield interesting information about m(vR) and g(R). The process of the Z2-boson single production in pp collisions is also considered. It is shown that it displays the extreme sensibility to both the g(R) and the PHI values.
