Solar neutrino problem7/5/2023 ![]() This problem has been largely solved by invoking a phenomenon known as neutrino oscillations, whereby neutrinos change form or “flavour” as they travel. It refers to the discrepancy between the number of neutrinos predicted by the standard solar model, and the number of neutrinos observed coming from the sun. ![]() The solar neutrino problem is a long-standing issue in astrophysics. What is the Solution to the Solar Neutrino Problem Quizlet This explanation for the solar neutrino problem is now widely accepted by scientists, and it provides an important piece of evidence for our understanding of particle physics. The heavier two types (muon and tau) are more likely to disappear, while the lighter one (electron) is more likely to reach us here on Earth. Since then, further research has shown that this oscillation is due to a difference in the mass of the three types of neutrinos. This discovery solved the solar neutrino problem, as it explained why we were seeing fewer neutrinos than expected. This meant that some of the neutrinos were “disappearing” and not reaching Earth. In 2001, researchers at the Sudbury Neutrino Observatory in Canada found that neutrinos originating from the Sun were actually oscillating between three different states. ![]() ![]() This problem has puzzled scientists for over three decades, but there may finally be a possible solution. It is the discrepancy between the number of neutrinos predicted by the Standard Solar Model, and the number of neutrinos observed coming from the Sun. The solar neutrino problem is a long-standing puzzle in astrophysics. ![]()
