abstract
A few multiplets that can be added to the SM contain a lightest neutral component which is automatically stable and provides allowed DM candidates with a non-standard phenomenology. Thanks to coannihilations, a successful thermal abundance is obtained for well defined DM masses. The best candidate seems to be a SU(2)_L fermion quintuplet with mass 4.4 TeV, accompanied by a charged partner 166 MeV heavier with life-time 1.8 cm, that manifests at colliders as charged tracks disappearing in pi^\pm with 97.7% branching ratio. The cross section for usual NC direct DM detection is sigma_SI = f^2 1.0 10^-43 cm^2 where f ~ 1 is a nucleon matrix element. We study prospects for CC direct detection and for indirect detection.

One-loop weak corrections to fermionic MDM annihilation cross sections are computed, with IR divergences canceling in the s-wave and 5% effects in doublet, triplet, and quintuplet cases.
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.
A double right-handed U(1) gauge extension generates the Standard Model fermion mass hierarchy at tree and loop levels and stabilizes a viable scalar singlet dark matter particle consistent with relic density and direct detection bounds.
A three-loop radiative neutrino mass model with vectorlike leptons and scalar dark matter that fits oscillation data, dark matter constraints, and lepton flavor violation bounds while predicting testable signals.
Recast LHC searches yield a ~1.2 TeV lower bound on long-lived charged dark mesons and show that anomaly-driven diboson resonances can reconstruct UV parameters like dark flavor and color numbers from IR measurements.
The thesis presents a new 3-to-2 freezeout mechanism, bound-state effects on searches, a new axion interferometric search, reionization assessments, 21-cm constraints, and the DarkHistory code for ionization and thermal histories.
Ultrarelativistically decoupling dark matter in Z' portal models has direct detection cross sections that existing experiments like LZ and XENONnT have already excluded over large regions, leaving testable space above the neutrino fog for 0.4 GeV to 1 TeV masses.
A largely model-independent framework links dark matter annihilation, mediator decays, and semi-annihilation to both thermal freeze-out and present-day gamma-ray, neutrino, and antimatter fluxes, with benchmarks showing how their relative strengths shape observable spectra.
Only the hypercharge-zero fermionic electroweak triplet dark matter survives current relic density, direct detection, and indirect detection constraints among the minimal triplet extensions considered.
Thesis summarizing an upper limit of 0.12 eV on the neutrino mass sum, bias calibration via CMB lensing cross-correlations, and tighter limits plus stronger normal-ordering preference in non-phantom dynamical dark energy models.
Computes one-loop anomalous dimensions for EDM-generating operators in triplet and 5-plet Majorana fermion models, reporting O(10)% enhancement for triplet and factor greater than 2 for 5-plet.
Weak triplet models permit decoupling of neutrino magnetic moment from mass in minimal realizations but require delicate parameter adjustments for observable effects, and lose the decoupling in extended scenarios.
Review of confining dark sectors summarizing dark matter candidates, abundance mechanisms, discovery channels, and applications to the abundance similarity puzzle.
