The degree to which a particle interacts with the Higgs field determines its mass: particles interacting weakly with the Higgs field are light, while those that interact strongly with the Higgs field ...The degree to which a particle interacts with the Higgs field determines its mass: particles interacting weakly with the Higgs field are light, while those that interact strongly with the Higgs field are heavy. The Standard Model predicts that fields that fill all space should be associated with a particle - for example, as we've seen each of the four fundamental forces is associated with a vector boson particle. 1 The particle associated with the Higgs field is the Higgs boson.
