Year: 2024

Type: article

Abstract: In this work, we systematically calculate transition magnetic moments, radiative decay widths, and axial-vector coupling constants of octet hidden-charm molecular pentaquark states with different flavor representations in constituent quark model. We discuss the relations between transition magnetic moments and decay widths for pentaquark states. For octet pentaquark states with the 8 1 f and 8 2 f flavor representations, decay widths of the processes P ψ | 3 2 − ⟩ ( 1 2 + ⊗ 1 − ) → P ψ | 1 2 − ⟩ ( 1 2 + ⊗ 0 − ) γ and P ψ | 1 2 − ⟩ ( 1 2 + ⊗ 1 − ) → P ψ | 1 2 − ⟩ (
