a quark is a fundemental constituant of matter
Observed in 1968 through deep elastic scatter
We found that protons
aren't as simple as we thought
We thought they were solid particles but they are not
Protons in fact are made up of three separate pieces
It just gets more confusing as our knowledge increases
But that is what a quark is; It's a piece of a proton
And they also make up other things including the neutron
And with leptons and bosons, unless
something's amiss,
They make up everything that we can see and that we know exists
Things made up of quarks including protons and neutrons
Are composite particles that physicists call hadrons
Many types of hadrons are theoretically described,
But most exist for only very brief amounts of time
Quarks have electric
charge, color
charge,
mass and spin,
And having color
charge means they exist solely inside of
Other kinds of particles and cannot exist alone
Which is why quarks have never been studied on their own
Quarks can join together in
two different ways,
Baryons and Mesons, but most instantly decay
If a particle has three quarks, then it's a baryon,
And if there's one quark and and
anti-quark, then it is a meson
