The '''weak nuclear forceinteraction''' is a [[force]] the mechanism governing the interactions between how [[hadron]]s and [[lepton]]saffect one another.

===About The Weak Nuclear ForceInteraction===: The '''weak nuclear forceinteraction''' is one of the 4 [[Fundamental ForceInteractions|fundamental forcesinteractions]] governing the interaction between how [[particleSubatomic Particle|subatomic particles]]saffect one another.: The '''weak nuclear forceinteraction''' causes the [[Radioactive Decay|decay]] of [[particle]]s into other, more stable, [[particleSubatomic Particle|subatomic particles]]s.: The '''weak nuclear forceinteraction''' can allow [[neutron]]s to [[Radioactive Decay|decay]] into [[proton]]s.: The '''weak nuclear forceinteraction''' is mediated by the [[W-boson]] and [[Z-boson]].: The effective range of the '''weak nuclear forceinteraction''' is smaller than the [[diameter]] of a [[proton]]. ===Examples==={| class="wikitable"|+W-boson interactions for [[nucleon]]s.|[[File:FeynmanDiagramNeutronDecay.png|center|200px]]|[[File:FeynmanDiagramPositronEmission.png|center|200px]]|[[File:FeynmanDiagramElectronCapture.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |This [[Feynman Diagram]] shows the [[Weak Nuclear Interaction|weak interaction]] in which a [[neutron]] [[Radioactive Decay|decays]] into a [[proton]].| style="height:20px; width:200px; text-align:center;" |This [[Feynman Diagram]] shows the [[Weak Nuclear Interaction|weak interaction]] in which a [[proton]] [[Radioactive Decay|decays]] into a [[neutron]] via [[Positron Emission|positron emission]].| style="height:20px; width:200px; text-align:center;" |This [[Feynman Diagram]] shows the [[Weak Nuclear Interaction|weak interaction]] in which a [[proton]] [[Electron Capture|captures]] an [[electron]] to become a [[neutron]].|} {| class="wikitable"|+W-boson interactions for [[quark]]s|[[File:FeynmanDiagramDownDecay.png|center|200px]]|[[File:FeynmanDiagramUpDecay.png|center|200px]]|[[File:FeynmanDiagramQuarkElectronCapture.png|center|200px]]|-| style="height:20px; width:200px; text-align:center;" |This [[Feynman Diagram]] shows the [[Weak Nuclear Interaction|weak interaction]] in which a [[down-quark]] [[Radioactive Decay|decays]] into an [[up-quark]].
