Semileptonic decay

From Wikipedia, the free encyclopedia

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

K⁰ → e⁻ + νe + π⁺

This is to be contrasted with a hadronic decay such as K⁰ → π⁺ + π⁻. Semileptonic decays of neutral kaons have been used to study kaon oscillations.
