We consider higher-dimensional effective (EFT) operators consisting of fermion dark matter (DM) connecting to Standard Model (SM) leptons upto dimension six. Considering all operators together and assuming the DM to undergo thermal freeze-out, we find out relic density allowed parameter space in terms of DM mass ($m_\chi$) and New Physics (NP) scale ($\Lambda$) with one loop direct search constraints from XENON1T experiment. Allowed parameter space of the model is probed at the proposed International Linear Collider (ILC) via monophoton signal for both Dirac and Majorana cases, limited by the centre-of-mass energy $\sqrt s=$1 TeV, where DM mass can be probed within $m_\chi<\frac{\sqrt{s}}{2}$ for the pair production to occur and $\Lambda>\sqrt s$ for the validity of EFT framework.

  1. Probing Light Dark Particles in Neutrino Scattering Experiments

    hep-ph 2026-02 conditional novelty 5.0

    A dark fermion produced in neutrino scattering could be probed at DUNE's near detector up to cutoff scales near 1 TeV, beyond CHARM II and LEP, while current COHERENT/CONUS+ limits stay below LHC bounds.

  2. INTEGRAL, eROSITA and Voyager Constraints on Light Bosonic Dark Matter: ALPs, Dark Photons, Scalars, $B-L$ and $L_{i}-L_{j}$ Vectors

    hep-ph 2025-07 unverdicted novelty 5.0

    This work sets new upper limits on decay lifetimes and couplings for axion-like particles, dark photons, scalars, and B-L or L_i-L_j vector bosons using 511 keV line, X-ray continuum, and cosmic-ray flux observations.

  3. Super-Kamiokande Strongly Constrains Leptophilic Dark Matter Capture in the Sun

    astro-ph.HE 2025-01 unverdicted novelty 5.0

    Super-Kamiokande data constrains the DM-electron scattering cross-section for leptophilic dark matter to ~4e-41 cm2 below 100 GeV, exceeding direct detection by over an order of magnitude.

  4. From WIMP to FIMP during reheating: collider vs non-collider probes for p-wave annihilation

    hep-ph 2026-05 unverdicted novelty 4.0

    Collider experiments can strongly constrain p-wave-suppressed derivative operators and thereby limit reheating temperature, DM mass, and interaction scale needed to match observed DM abundance during reheating.
