It is my understanding that the Higgs Boson is a fluctuation of the Higgs field. It also is not very stable and decays into a plethora of other particles. If all other particles interact with the Higgs field "to give them mass", then it suggests that all other particles are also fluctuations in the Higgs field as well. To me this sounds like all particles interact with themselves (i.e. particles are fluctuations in Higgs field and interact with Higgs field??)
1) I am assuming this is not true or flawed. If so how does a fluctuation in the Higgs field (Higgs Boson) decay into a some other particle.
2) Is it the frequency of the fluctuation that determines what particle it is? Or is any fluctuation of Higgs field a Higgs Boson?
Edit: @dgh has informed me (in the comments) about particles and their respective fields. And that if a field is coupled to another one then there is always a probability of decaying into the other one, unless breaking conservation laws. I think that answers both questions. Thanks @dgh! But any more insight is welcomed!
