A Study on the Form Factors of Hadrons

The form factors of the heavy mesons like Bc+ , ηb, B0s, F+, B0 , D, ψ, ?, 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.
