abstract = {We investigate the external reverse shock region of
relativistic jets as the origin of X-ray afterglows of
jetted tidal disruption events (TDEs) that exhibit luminous
jets accompanied by fast-declining non-thermal X-ray
emissions. We model the dynamics of jet propagating within
an external density medium, accounting for continuous energy
injection driven by accretion activities. We compute the
time-dependent synchrotron and inverse Compton emissions
from the reverse shock region. Our analysis demonstrates
that the reverse shock scenario can potentially explain the
X-ray light curves and spectra of four jetted TDEs, AT
2022cmc, Swift J1644, Swift J2058, and Swift J1112. Notably,
the rapid steepening of the late-stage X-ray light curves
can be attributed jointly to the jet break and cessation of
the central engine as the accretion rate drops below the
Eddington limit. Using parameters obtained from X-ray data
fitting, we also discuss the prospects for $\gamma$-ray and
neutrino detection.},
