A Study on the Form Factors of Hadrons
Keywords:Form factor, heavy meson, deuteron, momentum transfer, scaling behaviour.
The form factors of the heavy mesons like Bc+ , Î·b, B0s, F+, B0 , D, Ïˆ,Â Ï•, proton and also deuteron are investigated in the framework of the statistical model for low momentum transfer Q in the range 0.01 â‰¤ Q2 â‰¤ 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.
