SU6 UNITARY SYMMETRY IN DIBARYON SYSTEMS

  • A picture of the dibaryon system is proposed. If the fundamental particles of SU6 group are three baryons p, n and Λ which have spin 1/2, then the dibaryon system must be classified according to SU6 group. SU6 group connect the strange analogy state of spin 0 with strange analogy state of spin 1. The "original" mass difference between Λ hyperon and nucleon leads to the SU6 symmetry breaking. Then, SU3 gives the mass relations between strange analogy states of same spin, and SU6 gives mass relations between the different strange analogy states of spin 0 and 1.

Abstract: A picture of the dibaryon system is proposed. If the fundamental particles of SU6 group are three baryons p, n and Λ which have spin 1/2, then the dibaryon system must be classified according to SU6 group. SU6 group connect the strange analogy state of spin 0 with strange analogy state of spin 1. The "original" mass difference between Λ hyperon and nucleon leads to the SU6 symmetry breaking. Then, SU3 gives the mass relations between strange analogy states of same spin, and SU6 gives mass relations between the different strange analogy states of spin 0 and 1.
