Structure of the ω baryon and the kaon cloud

We investigate the effects of the kaon cloud on the electromagnetic and axial-vector form factors of the omega(-) baryon within the framework of the chiral quark-soliton model. We first derive the profile function of the chiral soliton in such a way that the kaon Yukawa tail is properly produced self-consistently. Then, we compute the electromagnetic form factors of the omega(-) baryon. The results for the electromagnetic form factors are compared with the lattice data. We find that the results with the kaon tail are in better agreement with the lattice data than those obtained with the pion tail. We also study the axial-vector form factors of the omega(-) baryon, examining the effects of the kaon cloud.

Automated summary

In this study, the effects of the kaon cloud on the electromagnetic and axial-vector form factors of the omega(-) baryon were investigated using the chiral quark-soliton model. The results were compared with lattice data, and it was found that the results with the kaon tail were in better agreement with the lattice data than those with the pion tail. The effects of the kaon cloud on the axial-vector form factors of the omega(-) baryon were also studied.
