Relativistic Charge Form Factor of the Deuteron
Relativistic integral representation in terms of experimental neutron– proton scattering phase shifts alone is used to compute the charge form factor of the deuteron GCd(Q ). The results of numerical calculations of |GCd(Q)| are presented in the interval of the four–momentum transfers squared 0 ≤ Q ≤ 35 fm−2. Zero and the prominent secondary maximum in |GCd(Q)| are the direct consequences of th...
متن کاملNeutron Charge Form Factor and Quadrupole Deformation of the Nucleon∗
A quark model relation between the neutron charge form factor and the N → ∆ charge quadrupole form factor is used to predict the C2/M1 ratio in the N → ∆ transition from the elastic neutron form factor data. Excellent agreement with the electro-pionproduction data is found, indicating the validity of the suggested relation. The implication of the negative C2/M1 ratio for the intrinsic deformati...
متن کاملNeutron charge radius and the neutron electric form factor
For nearly forty years, the Galster parametrization has been employed to fit existing data for the neutron electric form factor, GnE, vs the square of the four-momentum transfer, Q 2. Typically this parametrization is constrained to be consistent with experimental data for the neutron charge radius. However, we find that the Galster form does not have sufficient freedom to accommodate reasonabl...
متن کاملElectric S-brane Solutions with a Parallel Charge Density Form on a Ricci-flat Factor Space
We generalize the previously studied cosmological solutions in D -dimensional gravity with an antisymmetric (p+2)form to the case when the spatial part of the metric is Ricci-flat rather than flat. These generalized solutions are characterized by a parallel self-dual or anti-self-dual charge density form Q of rank 2m and satisfy the condition Q > 0. As with the previous flat-space case, these e...
متن کاملK0 form factor and charge radius in a covariant Salpeter model.
The electromagnetic form factor for the K 0 is calculated in a covariant formulation of the Salpeter equation for q ¯ q-bound states, which has been presented recently for the mass spectrum, decay properties and form factors of the light pseudoscalar and vector mesons. The K 0 charge radius dependence on the difference between strange and down constituent quark mass is discussed.
