Semileptonic decay

Semileptonic decay

In particle physics the semileptonic decay of a hadron refers to a decay through the weak interaction in which one lepton (and the corresponding neutrino) is produced in addition to one or more hadrons.

An example of a semileptonic decay is::SubatomicParticle|Kaon0 → SubatomicParticle|Electron + SubatomicParticle|Electron antineutrino + SubatomicParticle|Pion+

This is to be contrasted with a hadronic decay such as SubatomicParticle|Kaon0 → SubatomicParticle|Pion+ + SubatomicParticle|Pion-. Semileptonic decays of neutral kaons have been used to study kaon oscillations.
