Non-supersymmetric spin-3/2 dark matter with baryon-violating portals can explain the relic abundance through UV and Boltzmann-suppressed freeze-in, with viable parameter space constrained by indirect detection, direct detection, and LHC monojet searches.

Self-consistent four-point functions in NR EFT with Keldysh-Schwinger formalism render Sommerfeld unitarization temperature-dependent and keep bound states on-shell in out-of-equilibrium decay even with finite-width Breit-Wigner spectra.
Electroweak SU(2)_L doublet fermion dark matter with mass above 10^10 GeV (or 300 GeV if pseudo-Dirac) is produced by Boltzmann-suppressed freeze-in above the reheat temperature and evades direct detection while never thermalizing.
Temperature-dependent DM couplings mediated by a scalar field's VEV that drops after a first-order phase transition allow sufficient early-universe annihilations for the observed relic density while evading current direct detection bounds.
Dark sector first-order phase transitions near 10 MeV can substantially modify vector dark matter relic densities away from standard thermal freeze-out predictions, with distinct mass windows and calculable gravitational wave backgrounds.
Dipole dark matter produced by freeze-out or freeze-in, including entropy dilution from reheating, can be probed via neutron star heating due to momentum-dependent electromagnetic interactions.
