Pair Production of New Heavy Leptons with $U(1)'$ Charge at Linear Colliders

Understand

We study the pair production of new heavy leptons within a new $U(1)'$ symmetry extension of the Standard Model.

• Because of the new symmetry, the production and decay modes of the new heavy leptons would be different from those of three families of the standard model.
• The pair production cross sections depending on the mixing parameter and the mass of heavy leptons have been calculated for the center of mass energies of $0.5$ TeV, $1$ TeV and $3$ TeV.
• The accessible ranges of the parameters have been obtained for different luminosity projections at linear colliders.
