Symmetry selection rules restrict nucleon-pentaquark mixing to 6 of 27 positive-parity states, with sigma and pi transitions adding incoherently to a total five-quark probability of 29%.
The representative flavor⊗spin irreps relevant for the different total-spin sec- tors is summrized in Table II

Chiral Structure and Selection Rules in Light-Front Nucleon-Pentaquark Mixing
Symmetry selection rules restrict nucleon-pentaquark mixing to 6 of 27 positive-parity states, with sigma and pi transitions adding incoherently to a total five-quark probability of 29%.
