We derive the discovery potential of a leptophilic Z', and a Z' rising from a
SU(3)×SU(3)L×U(1)N symmetry at the Compact Linear Collider
(CLIC), which is planned to host e+e− collisions with 3 TeV center-of-mass
energy. We perform an optimized selection cut strategy on the transverse
momentum, pseudorapidity, and invariant mass of the dileptons in order to
enhance the collider sensitivity. We find that CLIC can potentially reach a
5σ signal of a 1−3~TeV leptophilic Z' with less than 1fb−1 of
integrated luminosity. As for the Z' belonging to a 3-3-1 symmetry, CLIC will
offer a complementary probe with the potential to impose MZ′>3~TeV
with L=2fb−1.Comment: 8 pages, 4 figure
