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. An example for this can be

→ 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.
