Experiments involving deep inelastic scattering provided the first significant evidence of their existence, and the Eightfold Way model was a predecessor of a model involving these particles.
A particle known as X(3872) may consist of four of these particles, an unstable type of which is known as the "sea" variety. Experiments involving deep inelastic scattering provided the first significant evidence of their existence, and the Eightfold Way model was a predecessor of a model involving these particles. Due to color confinement, they cannot exist in isolation, but only in the form of hadrons. For 10 points, name these particles which come in six flavors, including charm and bottom.
