DESCRIPTION:In this talk\, I will present a comprehensive analysis of lept
 on flavor-violating (LFV) dark matter (DM) interactions within an effectiv
 e field theory (EFT) framework\, covering both terrestrial and astrophysic
 al constraints. Working with leading-order effective leptophilic operators
  for three different flavor combinations (\\mu-e\, \\tau-e\, and \\tau-\\m
 u) and the three canonical DM candidates (scalar\, fermion\, and vector)\,
  we derive constraints from multiple complementary channels. On the terres
 trial side\, we analyze the three-body decay l_i -> l_j + DM + DM to const
 rain the effective interactions\, and then we discuss muonium invisible de
 cay following the constraints from the \\mu-e flavor scenario. On the astr
 ophysical side\, we utilize photon and positron data from Fermi-LAT\, INTE
 GRAL\, XMM-Newton\, and AMS-02\, accounting for final-state radiation\, ra
 diative decay\, and inverse Compton scattering contributions in the contex
 t of DM pair annihilation to different flavor charged leptons. These labor
 atory and astrophysical searches are complementary to each other\, togethe
 r placing stringent constraints on flavor-violating effective interactions
  across the kinematically accessible parameter space.\n\nhttps://indico.ib
