Description
In this talk, we present recent results of the leading-twist distribution amplitudes for the nucleon and $\Delta$ baryon within the framework of the chiral quark-soliton model. We first construct the light-cone wave functions to the five-quark state. By employing them, we then obtain the distribution amplitudes in the leading-twist accuracy. We find that it is essential to consider the five-quark component and relativistic corrections to evaluate the distribution amplitudes of the nucleon and $\Delta$ baryon. The results are consistent with the lattice data.
