A Study on the Form Factors of Hadrons

Abstract

The form factors of the heavy mesons like B_c⁺ , η_b, B⁰_s, F⁺, B⁰ , D, ψ,  Ï•, 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 observed that 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.
