A:
Joe,
I think what you are refering to is hadrons. Hadrons are not a
single kind of particle but instead is a large class of particles. A
hadron is any sub-atomic particle made from quarks. There are two kinds
of hadrons; baryons and mesons. Baryons contain three quarks while
mesons contain only two quarks. The most well known examples of hadrons
are the proton and the neutron. Both of these particles are baryons
because they each have three quarks. Protons and neutrons make up the
nuclei of all atoms. There are many more kinds of hadrons. There is the
pi particle which is a meson and many others. The quarks inside the
hadrons are held together by what physicists call the strong nuclear
force. This force is incredibly strong but acts only over a short
distance. This makes hadrons difficult to break apart.
