Abstract
Littlest Higgs (LH) model predicts the existence of the doubly charged
scalars Φ^±±, which generally have large flavor changing couplings
to leptons. We calculate the contributions of Φ^±± to the lepton
flavor violating (LFV) processes l_i→ l_jγ and l_i→
l_jl_kl_k, and compare our numerical results with the current
experimental upper limits on these processes. We find that some of these
processes can give severe constraints on the coupling constant Y_ij and the
mass parameter M_Φ. Taking into account the constraints on these free
parameters, we further discuss the possible lepton flavor violating signals of
Φ^±± at the high energy linear e^+e^- collider (ILC)
experiments. Our numerical results show that the possible signals of
Φ^±± might be detected via the subprocesses e^±e^±→
l^±l^± in the future ILC experiments.
