| Feb 27, 2020 at 14:40 | comment | added | Richter65 | Thank you @Asteroids! @TLW, to follow up on what PLL said (which was correct), there are various ways of experimentally measuring the fraction of neutrinos that get detected when they pass through a detector. The modern and most direct way is to create a neutrino beam of known intensity using a particle accelerator, and measuring the fraction of the beam that gets detected. A summary of these measurements can be found in the "bible of particle physics", the PDG: pdg.lbl.gov/2019/reviews/rpp2018-rev-nu-cross-sections.pdf | |

| Feb 26, 2020 at 8:51 | comment | added | PLL | @TLW: Just from the detected neutrino flux alone, you can’t tell. But if theoretical calculation A, about the sun’s output, says we should expect 1 billion neutrinos/sec, theoretical calculation B, about the detector, says we should expect to detect 10 per million of these, and we do indeed detect 10,000/s, then it’s less likely that both the theoretical calculations are wrong in ways that cancel out perfectly — especially when there are also other theoretical calculations C, D, and E that also agree with this, and experiments X, Y, Z that test other predictions of the theory. | |
| Feb 26, 2020 at 3:04 | comment | added | TLW | To play devil's advocate for a moment: how can you experimentally tell the difference between, say, 1 billion neutrinos / second of which 10/million are detected, and 10 billion neutrinos / second of which 1/million are detected? | |
