Because of the existence of sterile neutrino, how and why it gives effect on the big bang nucleosynthesis more than active-active neutrino oscillation. Its a question on behalf of my friend. thanks for any help
Haelfix said:Thats regarding the hypothesis for a light sterile neutrino. Nothing MiniBoone says effects the possibility of say a GUT induced one.
A sterile neutrino is a hypothetical particle that has been proposed to explain certain unexplained phenomena in particle physics. It is a neutral particle that does not interact with other particles through the strong or electromagnetic forces, and is therefore difficult to detect.
The existence of sterile neutrinos is important because it could help explain the observed discrepancies in the Standard Model of particle physics, such as the matter-antimatter asymmetry and the origin of dark matter. It could also provide insights into the nature of the universe and its fundamental particles.
Scientists have searched for sterile neutrinos through a variety of experiments, including neutrino oscillation experiments, which look for changes in the flavor of neutrinos as they travel through space. They have also searched for sterile neutrinos in high-energy particle collisions and through the detection of their decay products.
There have been several experiments that have reported potential detections of sterile neutrinos, but these results have not been confirmed by other experiments. The existence of sterile neutrinos is still a subject of ongoing research and debate in the scientific community.
If sterile neutrinos are confirmed to exist, it would require a significant revision of our understanding of particle physics. It could also have implications for our understanding of the evolution and composition of the universe. Additionally, the discovery of sterile neutrinos could lead to new technologies and applications in fields such as energy and medicine.
