Discussion Overview

The discussion revolves around the roles and properties of various quarks, specifically the strange, bottom, and charm quarks, in the context of particle physics. Participants explore their stability, interactions, and examples of materials formed from these quarks, touching on theoretical and conceptual aspects.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants note that strange, bottom, and charm quarks contribute to the formation of various materials.
  • Others mention that apart from neutron stars, these quarks are generally unstable in the universe.
  • Examples of particles formed from these quarks include kaons, J/ψ mesons, and B-mesons, as mentioned by participants.
  • One participant emphasizes that the top quark is so unstable that it does not appear in observable forms.
  • There is a suggestion to search for specific quark names online for more detailed examples and historical context.

Areas of Agreement / Disagreement

Participants express differing views on the stability and roles of these quarks, with no consensus reached regarding their overall contributions or stability in the universe.

Contextual Notes

Some claims depend on specific definitions of stability and the context of quark interactions, which remain unresolved in the discussion.

material made from up and down quark
but we have four more quark
what they are do??
 
Physics news on Phys.org
They make other materials.

example please..
 
Apart from the inner regions of neutron stars, they are not stable in our universe. They played an important role in the early universe, however.

We see these quarks in many mesons and also deduce their existence from some interactions.

An up or a down quark paired with a strange quark (incl antiparticles) gets you a kaon.
The charm quark-antiquark pair forms the J/ψ meson.
The B-meson includes the bottom quark.

mfb is correct, they do not make stable particles.
The top quark forms are so unstable they don't appear at all.

Just google for the name of the quark you are looking for and you'll find all the examples you can hope for. The wikipedia pages have a potted history telling you what was so special ... i.e. what is so strange about strange particles.
