Abstract
In this work, we calculate the magnetic moment and axial charge of the octet hidden-charm molecular pentaquark family in quark model. The Coleman-Glashow sum rule for the magnetic moments of pentaquark family is always fulfilled independently of SU(3) symmetry breaking. In the 82f flavor representation, the magnetic moments of hidden-charm molecular pentaquark states with spin configuration JP=12−(12+⊗0−) are all equal to μc=0.38μN. The axial charges of octet hidden-charm molecular pentaquark states are quite small compared to the axial charge of nucleon. The axial charges of the pentaquark states with the spin configuration JP=12−(12+⊗0−) in 82f flavor representation are all zero. Published by the American Physical Society 2024
