Particle Formation

[KuaRk(t)]

Hi!

I wanna learn particle only be form in only hadron collider or they can be form alone.(I mentioned particle:kaon,pion,...,)

It is difficult to tell from your post what you are actually asking. Am I correct in thinking that your question is whether or not particles like kaons and pions exist outside of hadron colliders?

 

If so, then yes. They are also formed in collisions of cosmic rays in the upper atmosphere. However, they are quite heavy, so decay very quickly. Since they are not stable, there are none in our normal everyday environment.
