Direct detection experiments for dark matter search for:
- Nuclear recoils from WIMP interactions
- Axion-photon conversion
- Sterile neutrino decay
- All of these
Answer: All of these
Multiple approaches: cryogenic detectors (WIMPs), haloscopes (axions), X-ray telescopes (sterile neutrinos). India participates in international collaborations (e.g., LUX-ZEPLIN). Understanding dark matter is key to cosmology. [[NCERT Physics Class 11, IUCAA Reports]]
