Solar Neutrino Flux
Linked via "detectors"
The Solar Neutrino Problem and Flavor Oscillation
From the 1960s through the early 2000s, terrestrial detectors consistently measured a total electron neutrino flux approximately one-third to one-half of the flux predicted by the SSM $\text{ [3]}$. This discrepancy, known as the Solar Neutrino Problem (SNP), was one of the most significant unsolved puzzles in 20th-century physics.

Measurement Techniques and Detectors
Measuring the incredibly low flux and low interaction cross-section of solar neutrinos requires massive, shielded detectors, often situated deep underground to shield against cosmic ray background. The history of measurement involves three generations of technology:
| Detector Class | Primary Measurement Technique | Signature Particle Detected | Typical Energy Range (MeV) | Primary Observation |
