Particles in Nature: Mesons, Baryons, Leptons

In summary, the conversation discusses the observation of mesons, baryons, and leptons in nature, specifically outside of artificial production. It is mentioned that muons and mesons containing strange are observed in cosmic ray collisions. The question is raised about whether electrons emitted from a thermionic cathode are considered artificially produced. The conversation also touches on the absence of top quarks in protons and the possibility of producing them through proton collisions. The individual asserts that they would like an explanation rather than useless posts.

Are mesons and baryons,other than protons and neutrons,observed in nature?where?
what about leptons,other than electrons,positrons and neutrinos?
thanks

What mesons, leptons, and/or baryons are you talking about?
 
  • #3
Muons are observed in cosmic ray collisions. So are mesons containing strange.

Where else is there?

Where else is there?
I mean not produced artificially.

What does that mean? Are electrons emitted from a thermionic cathode "artificially produced"? Give an example of something you consider that is not "artificially produced".

Many mesons, baryons, and leptons are observed in cosmic rays at high altitudes. Fortunately for us, most of them don't reach the earth.

Thanks meir
And Zapper you know what I mean so what's the point of such discussions?
there is no e.g. top quark in a proton,but When we collide two protons,we may get one.Maybe its not true but not so far,if we say that top quark is produced artificially.
If I'm wrong,explain it,don't give useless posts.(Sorry for being that direct and thank you for devoting time to this thread)
 

Related to Particles in Nature: Mesons, Baryons, Leptons

1. What are particles in nature?

Particles in nature refer to the fundamental building blocks of matter that make up the universe. These particles include mesons, baryons, and leptons.

2. What are mesons, baryons, and leptons?

Mesons are particles made of a quark and an antiquark, while baryons are particles made of three quarks. Leptons, on the other hand, are particles that do not interact through the strong nuclear force and include electrons, muons, and neutrinos.

3. How are mesons, baryons, and leptons different from each other?

Mesons and baryons are both hadrons, meaning they are composed of quarks and interact through the strong nuclear force. Leptons, on the other hand, do not interact through the strong nuclear force and are not composed of quarks.

4. What is the significance of particles in nature?

Particles in nature are significant because they make up all the matter in the universe. They also play a crucial role in the interactions between particles and the formation of atoms, molecules, and larger structures in the universe.

5. How do scientists study particles in nature?

Scientists study particles in nature through the use of particle accelerators, such as the Large Hadron Collider, and through experiments that detect and measure the properties of particles. They also use mathematical models and theories, such as the Standard Model, to understand the behavior of particles.
