Can Particle Interactions Reveal the Presence of Strong Interactions?

In summary, the process of yielding a photon involves an electromagnetic interaction, while a neutrino coming out indicates a weak interaction. It is possible to determine if a strong interaction is involved by examining the ingoing and outgoing particles. This can be confirmed if isospin and strangeness are conserved. The strong interaction is more likely to occur when both strong and weak conditions are fulfilled.

Whenever a process yields a photon, an electromagnetic interaction is involved. If a neutrino comes out, a weak interaction is responsible. Is there any way to see from the ingoing and outgoing particles if a strong interaction is involved?

if isospin and strangesness is conserved, you must have a strong intercation. Weak do not conserce strageness and EM do not conserve isospin.

Ah great, not as easy to figure out as for the other interactions but very helpful. Thanks!

And also the strong interaction is much much more probable than the weak in those cases when conditions of both strong and weak are fullfilled.
 

1. What are the different types of interactions between particles?

The four fundamental interactions between particles are the strong nuclear force, the weak nuclear force, electromagnetism, and gravity.

2. How do particles interact with each other?

Particles interact through the exchange of force-carrying particles, such as gluons, photons, and gravitons.

3. Can particles interact without touching each other?

Yes, particles can interact without touching each other through the exchange of force-carrying particles. This is known as a non-contact interaction.

4. What is the role of interactions in particle physics?

Interactions play a crucial role in understanding the behavior of particles and the fundamental forces that govern the universe.

5. How are interactions between particles studied?

Interactions between particles are studied through experiments, such as particle accelerators, and through theoretical models, such as quantum field theory.
