Abstract

The Vector gauge bosons Z' and axion-like particles (ALPs) a are predicted by the U(1)X gauge extension and Peccei-Quinn (PQ) models, respectively. We focus on the interactions of the Z' boson and the a particle with the W± gauge boson, and investigate the production cross section and related kinematic distributions for the Z'/a→ W+W- decay process at hadron colliders. We consider the angular distributions of charged leptons in the final states corresponding to the semileptonic and fully leptonic decays of the W± boson, separately. The study shows that, in the associated production processes of Z'/a with W+ or Z bosons, the angular distributions of final-state leptons can serve as an important observable for probing new gauge interactions, and can also provide a criterion to distinguish vector particles from pseudoscalar particles.

AB  - The Vector gauge bosons Z' and axion-like particles (ALPs) a are predicted by the U(1)_X gauge extension and Peccei-Quinn (PQ) models, respectively. We focus on the interactions of the Z' boson and the a particle with the W^± gauge boson, and investigate the production cross section and related kinematic distributions for the Z'/a→ W^+W^- decay process at hadron colliders. We consider the angular distributions of charged leptons in the final states corresponding to the semileptonic and fully leptonic decays of the W^± boson, separately. The study shows that, in the associated production processes of Z'/a with W^+ or Z bosons, the angular distributions of final-state leptons can serve as an important observable for probing new gauge interactions, and can also provide a criterion to distinguish vector particles from pseudoscalar particles.
