This paper investigates the magnetic moments and axial charges of the octet hidden-charm molecular pentaquark family using the quark model. The authors calculate the magnetic moments of these pentaquark states, which are found to be consistent with the Coleman-Glashow sum rule, independent of SU(3) symmetry breaking. In the $s_{2f}$ flavor representation, the magnetic moments of pentaquark states with the spin configuration $J^P = \frac{1}{2} ( \frac{1}{2}^+ \otimes 0^- )$ are all equal to $\mu_e = 0.38 \mu_N$. The axial charges of these pentaquark states are significantly smaller compared to the axial charge of the nucleon, and they are all zero for the states with the same spin configuration in the $8_{2f}$ flavor representation. The study provides valuable insights into the internal structure and electromagnetic properties of these exotic hadrons, which are crucial for understanding strong interactions and QCD at low energies. The results also highlight the sensitivity of axial charges to flavor-spin configurations, which can aid in distinguishing different pentaquark structures in future experiments.This paper investigates the magnetic moments and axial charges of the octet hidden-charm molecular pentaquark family using the quark model.
