  The sensitivity studies to observe long-lived particles predicted by a set of
beyond the Standard Model theoretical models are reported. The analysis is
based on a data sample of $e^+e^-$ collisions at sqrt(s) = 3 TeV, simulated
with the CLIC_ILD detector model and corresponding to an integrated luminosity
of 3 ab-1. Long-lived particle decay products are subsequently combined to
reconstruct the parent bosons employing secondary vertices displaced from the
beam axis. The upper limits on the production cross section for the long-lived
particle lifetimes from 1 to 300 ps, masses between 25 and 50 GeV/c2, and a
parent Higgs mass of 126 GeV/c2 are determined.
