Nucleon and flavor form factors in AdS/QCD    [PDF]

Dipankar Chakrabarti, Chandan Mondal
The electromagnetic form factors for the nucleons are related with the GPDs by sum rules. Using the sum rules we calculate the valence GPDs for $u$ and $d$ quarks in a quark model using the lightfront wavefunctions for the nucleons obtained from AdS/QCD. The flavor decompositions of the nucleon form factors are also calculated from the GPDs in this model. We show that the nucleon form factors and their flavor decompositions calculated in AdS/QCD are in agreement with experimental data.
