SUMMARY

The discussion focuses on the role of strange, charm, and bottom quarks in particle physics. It highlights that while up and down quarks form stable materials, strange, charm, and bottom quarks primarily exist in unstable states, such as mesons. Specific examples include the kaon, formed by an up or down quark paired with a strange quark, and the J/ψ meson, which consists of a charm quark-antiquark pair. The discussion emphasizes the historical significance of these quarks in the early universe and their presence in various particle interactions.

PREREQUISITES
  • Understanding of quark types: up, down, strange, charm, and bottom quarks

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.
