Asymptotic of the deuteron wave function in the coordinate representation and the charge deuteron form factor at large momentums

Numerical modeling of the deuteron wave function in the coordinate representation for the phenomenological nucleon–nucleon potential Argonne v18 has been performed. For this purpose, the asymptotic behavior of the radial wave function has been taken into account near the origin of coordinates and at infinity. The charge deuteron form factor [Formula: see text], depending on the transmitted momentums up to [Formula: see text], has been calculated employing five models for the deuteron wave function. A characteristic difference in calculations of [Formula: see text] is observed near the positions of the first and second zero. The difference between the obtained values for [Formula: see text] form factor has been analyzed using the values of the ratios and differences for the results. Obtained outcomes for charge deuteron form factor at large momentums may be a prediction for future experimental data.

A Study on the Form Factors of Hadrons

The form factors of the heavy mesons like Bc+ , ηb, B0s, F+, B0 , D, ψ, ϕ, proton and also deuteron are investigated in the framework of the statistical model for low momentum transfer Q in the range 0.01 ≤ Q2 ≤ 0.1 GeV2.It has been observedthat the heavy-light flavour mesonic form factors show a scaling behavior in the aforesaid low Q2 range. The proton form factor also shows almost scaling in the aforesaid range whereas the deuteron form factor shows a clear violation indicating large contribution from sea quarks and gluon sector.
