Semileptonic decay

Last updated

In particle physics the semileptonic decay of a hadron is a decay caused by the weak force in which one lepton (and the corresponding neutrino) is produced in addition to one or more hadrons. [1] An example for this can be

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. [2]

Semileptonic decays of neutral kaons have been used to study kaon oscillations. [3]
