Description

We apply Holographic QCD for study gluon and heavy quark content in the nucleon. In particular, we discuss the following results:

(1) sum rules, small and large x-behavior for the gluon TMDs [1];

(2) light-front representations and numerical results for the heavy quark-antiquark asymmetry, the electromagnetic form factors of nucleons induced by heavy quarks, including their magnetic moments and radii [2].
