What happens to Fermions during Beta decay radiation?

Click For Summary

Discussion Overview

The discussion centers on the behavior of fermions, specifically quarks and leptons, during beta decay. Participants explore the creation of electrons or positrons and the flavor change of quarks in this process, delving into the underlying mechanisms and principles of particle interactions.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant expresses confusion about the processes involved in beta decay, particularly regarding the creation of electrons or positrons and the flavor change of quarks.
  • Another participant asserts that particles can be created or destroyed during interactions without a deeper mechanism, emphasizing that this applies to both fermions and bosons.
  • A further response reiterates the idea of particle creation, stating that as long as conserved quantities are maintained, particles can emerge seemingly from nothing, and suggests that the nature of these interactions can be described by quantum field theory.
  • There is a suggestion that inquiries into the "how" of these processes may lead to unproductive loops of questioning, implying a limit to the explanatory power of current understanding.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the deeper mechanisms behind particle creation during beta decay, with some emphasizing the simplicity of the process while others seek a more detailed explanation.

Contextual Notes

The discussion reflects varying levels of understanding regarding the fundamental principles of particle physics, particularly in relation to conservation laws and quantum field theory. There are unresolved questions about the nature of particle interactions and the limits of explanation in this context.

I recently started learning about quarks and leptons and was wondering what happens to the fermions (specifically the quarks and leptons) during a beta decay. How is the electron/positron created and what causes the up quarks and down quarks to change flavours?
If this is a bad question please feel free to ignore it I am just confused as to how it all would work.
Thank you:smile:

The particles are simply created or destroyed in interactions. There is no deeper mechanism for that. This applies to bosons as well.

But how is there suddenly an electron/positron?
 
It is created.
Particles can be created just like that as long as all conserved quantities are conserved (like energy, momentum, lepton number and so on).

Quantum field theory describes it as interaction between fields but the basic idea is still the same: It just happens. You can keep asking "how" forever but you won't get a useful answer forever. It's just how nature is.
