Abstract

The nucleon form factors of the energy-momentum tensor are studied in the large-N_c limit in the framework of the chiral quark-soliton model for model parameters that simulate physical situations in which pions are heavy. This allows for a direct comparison to lattice quantum chromodynamics results.
