AbstractIn this work, we employ the light-cone QCD sum rule to calculate the magnetic dipole moments of the $$P_c(4440)$$ P c ( 4440 ) , $$P_c(4457)$$ P c ( 4457 ) and $$P_{cs}(4459)$$ P cs ( 4459 ) pentaquark states by considering them as the diquark–diquark–antiquark and molecular pictures with quantum numbers $$J^P = \frac{3}{2}^-$$ J P = 3 2 - , $$J^P = \frac{1}{2}^-$$ J P = 1 2 - and $$J^P = \frac{1}{2}^-$$ J P = 1 2 - , respectively. In the analyses, we use the diquark–diquark–antiquark and molecular form of interpolating currents, and photon distribution amplitudes to obtain the magnetic dipole moment of pentaquark states. Theoretical examinations on magnetic dipole moments of the hidden-charm pentaquark states, are essential as their results can help us better figure out their substructure and the dynamics of the QCD as the theory of the strong interaction. As a by product, we extract the electric quadrupole and magnetic octupole moments of the $$P_c(4440)$$ P c ( 4440 ) pentaquark. These values show a non-spherical charge distribution.

New Formulation

In this work, we propose a new formulation allowing to realize the holonomic quantum computation with neutral particles with a permanent magnetic dipole moments interacting with an external electric field in the presence of a topological defect. We show that both the interaction of the electric field with the magnetic dipole moment and the presence of topological defect generate independent contributions to the geometric quantum phases which can be used to describe any arbitrary rotation on the magnetic dipole moment without using the adiabatic approximation.

The Moment

The binding energy, the root-mean-square radius, the magnetic dipole moment, the electric quadrupole moment, and the moment of inertia of the nucleus 6Li are calculated by applying different models. The translation invariant shell model is applied to calculate the binding energy, the root-mean-square radius, and the magnetic dipole moment by using two- and three-body interactions. Also, the spectra of the nuclei with A = 6 are calculated by using the translation-invariant shell model. Moreover, the ft-value of the allowed transition: 6He(Jπ=0+;T=1)β- → 6Li(Jπ=1+;T'=1) is also calculated. Furthermore, the concept of the single-particle Schrodinger fluid for axially symmetric deformed nuclei is applied to calculate the moment of inertia of 6Li. Also, we calculated the magnetic dipole moment and the electric quadrupole moment of the nucleus 6Li in this case of axially symmetric shape. Moreover, the nuclear superfluidity model is applied to calculate the moment of inertia of 6Li, based on a single-particle deformed anisotropic oscillator potential added to it a spin-orbit term and a term proportional to the square of the orbital angular momentum, as usual in this case. The single-particle wave functions obtained in this case are used to calculate the magnetic dipole moment and the electric quadrupole moment of 6Li.

The nuclear magnetic dipole moment of 151 Eu and the ratio of the moments of 151 Eu and 153 Eu have been measured by the new method of resonance in three loops in a short atomic beam. The results are: μ ( 151 Eu) = 3·419 ± 0·004 n.m.; μ ( 151 Eu) / μ ( 153 Eu)= 2·2686 ± 0·0015. The result, taken together with the ratio of the hyperfine structures of europium, gives a hyperfine structure anomaly of (1·0 + 0·23)%. A theoretical value of the anomaly is estimated.

Minimal Supersymmetric Extension

Using the effective Lagrangian method, we study the electroweak corrections to the magnetic dipole moment of muon from some special two-loop topological diagrams which are composed of chargino–sneutrino, neutralino–slepton, slepton–sneutrino, in the CP-violating minimal supersymmetric extension of the standard model. Considering the electromagnetic gauge invariance, we obtain the Wilson coefficients of those dimension 6 operators which induce the magnetic dipole moment of leptons. Adopting the zero-momentum substraction scheme, we remove the ultra-violet divergences induced by the divergent sub-diagrams. The numerical results indicate that the two-loop supersymmetric corrections from this sector to the muon magnetic dipole moment can exceed 10-10, which is the same order of present experimental precision.

Two Higgs Doublet Models

In several frameworks for leptons sectors of Two Higgs Doublet Models, we calculate the magnetic dipole moment for different flavor types of neutrino. Computations are carried out by assuming a normal hierarchy for neutrino masses, and analyzing the process [Formula: see text] with a charged Higgs boson into the loop. The analysis was performed by sweeping the charged Higgs mass and taking into account the experimental constraints for relevant parameters in Two Higgs Doublet Models with and without flavor changing neutral currents; obtaining magnetic dipole moments close to the experimental thresholds for tau neutrinos in type II and lepton-specific cases. In the neutrino-specific scenario, the contribution of new physics could be sizeable to the current measurement for flavor magnetic dipole moment. This fact leads to excluding possible zones in the parameter space of charged Higgs mass and vacuum expectation value of the second doublet.
