We study the possible dynamics associated with leptonic charge in future linear colliders. Leptophilic massive vector boson, Zl, have been investigated through the process e+e?→Uμ +Uμ?. We have shown that ILC and CLIC will give opportunity to observe Zl with masses up to the center of mass energy if the corresponding coupling constant g1 exceeds 10?3.© 2011 SISSA.
