For 10 points, name these elementary particles that come in bottom, down, up, top, strange, and charmed varieties.
For one of these particles, a rotation matrix whose angle is the Cabibbo angle describes the probability of the weak force converting one of them into another. The force between two of these particles does not diminish with increasing distance, leading them to cluster in small groups. That force between these particles approaches zero at small distances. These particles are subject to confinement and asymptotic freedom. These particles can possess charges such as +2/3 and -1/3. Three of them combine to form a baryon such as a proton or neutron, and they are linked by gluons.
