I am having a question in mind that why π+ decays to muon and muonic neutrino ,why no electron and electronic neutrino?
arivero said:It is always amusing to consider that if the mass of muon and pion were the same, the pion would be an stable particle at tree level, wouln't it?
arivero said:Well, considering also that the mass of electron is practically zero.
It would still decay to electron plus neutrino. Its lifetime would be a factor 10,000 larger, but that is still just 0.25 milliseconds.arivero said:It is always amusing to consider that if the mass of muon and pion were the same, the pion would be an stable particle at tree level, wouln't it?
π+ decay is a type of radioactive decay in which a positively charged pion (π+) particle transforms into a muon (μ) particle and a muonic neutrino (νμ).
This decay occurs because the π+ particle is unstable and has too much energy to remain in its current state. In order to become more stable, it transforms into a muon and a muonic neutrino, which are more stable particles.
Muons are elementary particles that are similar to electrons but have a larger mass. They are unstable and typically decay into other particles. Muonic neutrinos are neutral particles that have very little mass and interact very weakly with matter. They are produced in various particle decay processes.
This decay process is important for understanding the nature of subatomic particles and their interactions. It also helps scientists to study the properties of muons and muonic neutrinos, which can provide insights into the fundamental laws of physics.
Scientists use particle accelerators to create high-energy collisions that produce π+ particles. They then study the decay products, including muons and muonic neutrinos, to gather information about their properties and interactions. This research helps to advance our understanding of the universe at a subatomic level.
