“…The study of the electromagnetic properties of the deuteron has a long and rich history (for some recent reviews, see, e.g. [1]- [4]). The deuteron, as a spin-1 particle, is usually believed to be a weakly bound system of a proton and a neutron with a binding energy ǫ D ∼ 2.22 MeV.…”

“…The theoretical study of eD elastic scattering and deuteron EM form factors has been performed in different approaches [7]- [15]: potential models, phenomenological models including quark, meson and nucleon degrees of freedom, effective field theories, etc. (for an overview see [1]- [4]). In the present work we apply a phenomenological Lagrangian approach to study the EM form factors of the deuteron.…”

Phenomenological Lagrangian approach to the electromagnetic deuteron form factors

et al. 2008

A phenomenological Lagrangian approach is employed to study the electromagnetic properties of the deuteron. The deuteron is regarded as a weakly bound state of the proton and neutron. We construct a general form for the electromagnetic one-and two-body transition operators formulated in terms of the nucleon fields, which are then used in the calculation of the electromagnetic deuteron form factors. One of the two-body operators is responsible for explaining the quadrupole moment form factor. We show that in our approach the data on the deuteron form factors as well as on the differential cross section of elastic electron-deuteron scattering are well explained.

We review the features of the pomeron in the S-matrix theory and in quantum field theory. We extend those general properties to the pomeron of closed bosonic string theory in a Minkowskian background. We compute the couplings of the pomeron to the lowest mass levels of closed bosonic string states in flat space. We recognize the deviation from the linearity of the Regge trajectories in a five dimensional anti De Sitter background.

“…Furthermore, in a spin-1 system, for instance a deuteron or a vector ρ-meson, the charge, magnetic and quadrupole form factors can also reveal its intrinsic structures, such as its charge and magnetic distributions and the quadrupole deformation (see, for example, Refs. [25][26][27][28][29][30][31] for the deuteron and Refs. [32][33][34][35][36][37][38] for the ρ meson, respectively).…”

Form factors of the d*(2380) resonance

In order to explore the possible physical quantities for judging different structures of the newly observed resonance d Ã ð2380Þ, we study its electromagnetic form factors. In addition to the electric charge monopole C0, we calculate its electric quadrupole E2, magnetic dipole M1, and magnetic octupole M3 form factors on the base of the realistic coupled ΔΔ þ C 8 C 8 channel dÃ wave function with both the S-and D-partial waves. The results show that the magnetic dipole moment and electric quadrupole deformation of d Ã are 7.602 and 2.53 × 10 −2 fm 2 , respectively. The calculated magnetic dipole moment in the naive constituent quark model is also compared with the result of D 12 π picture. By comparing with partial results where the d Ã state is considered with a single ΔΔ and with a D 12 π structures, we find that in addition to the charge distribution of d Ã , the magnetic dipole moment and magnetic radius can be used to discriminate different structures of d Ã . Moreover, a quite small electric quadrupole deformation indicates that d Ã is more inclined to a slightly oblate shape due to our compact hexaquark dominated structure of d Ã .
