Model-Independent Analysis of the Indirect Effects of an Additional Z'-Boson at CLIC

D. V. Sinegribov, V. V. Andreev, and I. A. Serenkova

In this paper, we present a technique for analyzing the indirect manifestation of an additional Z'-boson in the planned experiments at future e⁺e⁻ colliders. The developed technique is based on the representation of the differential cross section for the process e⁺e⁻→ a ā (where a ≠ e) incorporating new effective parameters of the Z'-boson. The availability of the electron polarization option plays a key role in the implementation of the technique. As a result, we obtained model-independent constraints on the characteristics of the Z'-boson, taking into account the experimental capabilities of CLIC.

Key words: Compact Linear Collider, beyond the Standard Model, Z' gauge boson
