    Decay
In summary, The conversation discusses the K+ decay process and the question of its speculation. The PDG mesons summary table shows the decay without a Feynman diagram, but the diagram includes a w+ boson and a gluon. The question is whether there are alternative routes to this decay that have been proposed. The conversation also mentions that everything that is possible will occur if we wait long enough, and that nature does not "calculate" decays using perturbation theory and Feynman diagrams. The question is asked about what the person does not like about this process and why they believe it may be "too much for nature to do". It is mentioned that this particular decay only happens about 5% of the time.

Please see the attcahed image of K+ decay...

Question is - does anyone know how speculative this decay process is?? It just seems so far fetched.

you can look it up in the particle data group booklet

Yes, I saw it in the PDG mesons summary table, albeit without a feynman diagram. The feynman diagram shows everything between the up (at the top of the diagram) and the anti-up (at the bottom) comming from a w+ boson, half of it from a subsequent massive decay from a gluon. Being naive, it seems a bit much for nature to do.

My actual question is, does anyone know of any arlternative routes to this decay that have been proposed? All of my searches keep comming back to this one.

thanks

everything that is possible will occur if we wait long enough

recall that that is just one diagram in the full perturbation expansion of the scattering matrix, nature does not "calculate" decays with perturbation theory and feynman diagrams I think ;- )

What don't you like about this? why do you think it is "too much for nature to do"? (And remember, this only happens about 5% of the time)
 

Related to K+ Decay: Speculative or Feasible?

1. Is K+ Decay a speculative or feasible process?

K+ Decay, or the decay of a positively charged kaon particle, is a speculative process. This means that it has not been definitively proven through experiments, but is based on theoretical calculations and predictions.

2. What is the theoretical basis for K+ Decay?

The theoretical basis for K+ Decay is the Standard Model of particle physics, which explains the fundamental particles and forces of the universe. According to the Standard Model, Kaon particles can decay into a pion particle and a neutrino, with the emission of an electron or a positron.

3. How does K+ Decay differ from other types of particle decay?

K+ Decay differs from other types of particle decay, such as beta decay, because it involves the decay of a kaon particle, which is a meson. Other types of decay involve different types of particles, such as protons or neutrons.

4. What evidence supports the feasibility of K+ Decay?

Although K+ Decay has not been directly observed, there is strong evidence supporting its feasibility. This includes theoretical calculations, as well as indirect evidence from other experiments and observations that are consistent with the predictions of the Standard Model.

5. How can we test the speculative nature of K+ Decay?

To test the speculative nature of K+ Decay, scientists can conduct experiments to directly observe and measure the decay process. This can be done through high-energy particle accelerators, where kaon particles can be produced and observed. If the results are consistent with the predictions of the Standard Model, it would provide further evidence for the feasibility of K+ Decay.
