It seems that no matter how far and wide I look, I can find no concise explanation as to the roles of bosons in a nuclear reaction, fusion and/or fission. Thus, my inquiry: What role do bosons play in nuclear reactions, fusion and fission? What is the sequence of events that result in such a nuclear reaction, with regards to both fermions and bosons? Time and time again I read about the neutrons being given off as a particle decays, accompanied by "a great amount of energy." What is this energy in the form of? Is the energy in the form of gluons? W & Z bosons? Photons? A combination thereof? For example: In a nuclear bomb, as the reaction is triggered, a series of events leads to that enormous amount of energy given off. What is this series of events at the elementary particle level? Are, say, neutrons ejected along with gluons or what have you which then go on to continue the reaction with the adjacent particles? What is the actual scenario?
