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

K0  e + ν
e
 + π+

This is to be contrasted with purely hadronic decays, such as K0  π+ + π, which are also mediated by the weak force.

Semileptonic decays of neutral kaons have been used to study kaon oscillations.
