Description
Neutrinos and dark matter dominate the invisible universe, representing fundamental challenges in modern physics. This review examines advanced detector technologies and methodologies driving progress in understanding these elusive components, with emphasis on cosmological significance and synergies uniting particle physics, astrophysics, and cosmology.
The field of neutrino physics now achieves unprecedented precision through large-scale detector systems. Neutrino oscillation parameter quantification advances through reactor-based installations exemplified by JUNO, while long-baseline accelerator facilities including DUNE resolve CP-violation phases and mass hierarchy configurations. Extreme-environment astrophysical neutrino detection operates via IceCube and KM3NeT observatory networks. Complementary methodologies - notably KATRIN's tritium β-decay spectroscopy and Project 8's cyclotron radiation detection - progressively constrain the absolute neutrino mass parameter, critically impacting cosmological tension resolution such as Hubble constant discrepancies.
Indirect detection methodologies employ space-based instrumentation including Fermi-LAT, AMS-02, and JWST to identify dark matter annihilation signatures across electromagnetic bands. Theoretical frameworks propose geometric reformulations of dark matter distributions - from hyperbolic halo density profiles to torsion-modified spacetime metrics - addressing persistent anomalies like the galactic core-cusp problem within U(1)'-symmetric dark sectors.
Multi messenger astrophysics exploits emergent observational synergies through spatiotemporal correlations between IceCube neutrino events and LIGO-Virgo-KAGRA gravitational wave signatures, augmented by Vera Rubin Observatory's weak gravitational lensing surveys. These convergences potentially elucidate dark matter-neutrino coupling mechanisms within compact binary merger environments. Next-generation facilities (DARWIN, IceCube-Gen2, ARIA) target zeptobarn-scale sensitivity via:
- Advanced photodetection and charge-readout systems
- Scalable architectures inspired by GridPix technology
- Machine learning-driven signal discrimination
-Paleo-detectors utilizing mineral inclusions for multi-gigayear neutrino flux reconstruction
This review synthesizes how experimental advances—from kiloton-scale neutrino detectors to ultra-low-background chambers—are elucidating the invisible universe, charting a trajectory at the intersection of fundamental physics and cosmic discovery.
