Why do pions decay of muons

This "electronic mode" was discovered at CERN in The Pion decays in an electromagnetic force process. The rate at which Pions decay is a prominent quantity in many sub-fields of particle physics, such as Chiral-Perturbation theory.

This rate is parametrized by the Pion decay constant , related to the wave function overlap of the Quark and anti-Quark. In their work, researchers in the field of particle physics are looking for ways of simulating pion decay, and this is where the need for an Arbitrary Waveform Generator arises.

The unit has a typical rise time of ps and can reach amplitudes of up to 4Vpp. Improve this answer. Community Bot 1. Daniel Griscom 3, 4 4 gold badges 17 17 silver badges 34 34 bronze badges.

The only difference is that being heavier, the muon can decay into an electron, which it does in a time of 2. At first, physicists believed that it was the particle we now know as the pion.

The pion is only about 30 per cent heavier than the muon, but it behaves very differently. Whereas the muon is uninfluenced by the strong force that works inside the nucleus, the pion plays a role in binding protons with neutrons. This means that high-energy muons can penetrate far into matter before they interact or decay; indeed, some cosmic-ray muons travel hundreds of metres below ground.
