Influence of the Z-Z' mixing on the Z' production cross section in the model-independent approach
Abstract
The new module SMZp is developed for the Monte-Carlo generator Sherpa that extends simulations of the Standard model (SM) processes with the Abelian Z' boson in the model-independent approach. The special derived earlier relations between the Z' couplings to the SM fields proper to the renormalizable theories are taken into account. Using this module, dependence of the Z' production cross section on the Z-Z' mixing angle θ0 in the Drell-Yan process is investigated within the range of 1 TeV ≤ mZ' ≤ 5 TeV. It is shown that if it is essential to keep the Z' theory renormalizable, θ0 cannot be neglected as it is often done, even if it is small.
