Discussion Overview

The discussion revolves around the observation of mesons, baryons, and leptons in nature, specifically questioning the existence of these particles beyond protons, neutrons, electrons, positrons, and neutrinos. The scope includes theoretical and experimental aspects of particle physics, with a focus on naturally occurring versus artificially produced particles.

Discussion Character

  • Exploratory
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • Some participants inquire about the existence of mesons and baryons other than protons and neutrons, asking for specific examples of where they can be observed in nature.
  • One participant mentions that muons and strange mesons are observed in cosmic ray collisions.
  • Another participant emphasizes the need for examples of particles that are not produced artificially, questioning the definition of "artificially produced" in the context of particle observation.
  • It is noted that many mesons, baryons, and leptons are detected in cosmic rays at high altitudes, although most do not reach the Earth's surface.
  • A participant expresses frustration over perceived unproductive posts and seeks clarification on the distinction between naturally occurring and artificially produced particles, using the top quark as an example.

Areas of Agreement / Disagreement

Participants express differing views on what constitutes "artificially produced" particles and whether certain particles can be considered naturally occurring. The discussion remains unresolved regarding specific examples and definitions.

Contextual Notes

There are limitations in the definitions of "artificially produced" and "naturally occurring" particles, as well as the scope of examples provided. Some assumptions about the context of particle observation may not be fully articulated.

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?
 
Muons are observed in cosmic ray collisions. So are mesons containing strange.
 
Are mesons and baryons,other than protons and neutrons,observed in nature?
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)
