I presume they cannot as they are fundamental particles? But then a meson can decay into a lepton?
Note that being a fundamental particle has nothing to do with being able to decay or not. There are unstable fundamental particles and there are stable composite particles.Soffie said:I presume they cannot as they are fundamental particles?
If we neglect neutrino mixing in the decay, it has to be at least one tau neutrino.Orodruin said:If this is a neutrino it is typically not seen in the detector.
Leptons are elementary particles that make up matter, such as electrons, muons, and neutrinos. Mesons are also elementary particles, but they are made up of a quark and an antiquark, which are the building blocks of protons and neutrons.
Yes, leptons can decay into mesons through the weak interaction, one of the four fundamental forces of nature. This process is known as lepton flavor violation.
The decay of leptons into mesons is an important phenomenon in particle physics as it provides evidence for the violation of lepton flavor conservation, which is the principle that the number of leptons of each type (electron, muon, and tau) remains constant. This violation is a key area of study in understanding the fundamental laws of nature.
This decay process is studied through high energy particle accelerators, where leptons and mesons are produced and their decays are observed. Scientists also use detectors to measure the properties of the particles involved in the decay.
The decay of leptons into mesons is currently not fully explained by the Standard Model, which is the current theory that describes the behavior of subatomic particles. This phenomenon suggests the existence of new physics beyond the Standard Model, and studying it could provide insights into the mysteries of the universe.
