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

We develop an approach based on the light-cone sum rules at the leading order of α_S to calculate the gravitational form factors A (t ) and B (t ) for the valence quark combinations in a 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.
