Gravitational form factors within light-cone sum rules at leading order

Abstract

We develop an approach based on the light-cone sum rules at the leading order of ${\alpha }_S$ to calculate the gravitational form factors $A(t)$ and $B(t)$ for the valence quark combinations in nucleon. Within the proposed model, the predictions for the gravitational form factor $D(t)$ ($D$-term contributions) have been presented. Comparison with the experimental data and with the results of different models is discussed.
