Strong force fields and stabilities of the nucleon and singly heavy baryon Σc

초록

We investigate the strong force fields and stabilities of the nucleon and the singly heavy baryon Sigma(c) within the framework of the chiral quark-soliton model. Having constructed the pion mean fields in the presence of the N-c - 1 level quarks self-consistently, we are able to examine the gravitational form factors of Sigma(c). We mainly focus in the present work on the stability conditions for both the nucleon and Sigma(c) and discuss the strong force fields and their physical implications. We also present the results for the gravitational form factors and relevant observables, emphasizing the difference between the nucleon and Sigma(c).
