A magnetic moment fluctuates in both longitudinal and transverse directions. The total moment sum rule is a conservation law that can help us resolve data of neutron scattering into the two components.

AbstractIn this paper, we tentatively assign the $$P_{c}(4312)$$ P c ( 4312 ) to be a $$\bar{D}\Sigma _{c}$$ D ¯ Σ c molecular state with quantum number $$J^{P}=\frac{1}{2}^{-}$$ J P = 1 2 - , and calculate its magnetic moment using the QCD sum rule method in external weak electromagnetic field. Starting with the two-point correlation function in external electromagnetic field and expanding it in power of the electromagnetic interaction Hamiltonian, we extract the magnetic moment from the linear response to the external electromagnetic field. The numerical value of the magnetic moment of $$P_{c}(4312)$$ P c ( 4312 ) is $$\mu _{P_{c}}=1.75^{+0.15}_{-0.11}$$ μ P c = 1 . 75 - 0.11 + 0.15 .
