Abstract
We have presented a pathway to map the internal structure of lowest-lying octet baryons by using one-loop quantum fluctuations of a fermion state in Yukawa theory. The structural interpretation of baryons carrying different amount of strange content has been exemplified by employing a quark-scalar diquark model for studying the Generalized Parton Distributions (GPDs) among the members of octet baryons. Different possible combinations of quark-scalar diquark pairs have been considered. The quark helicity independent chiral even GPDs in momentum as well as impact parameter space have been studied for purely transverse momentum transfer (zero skewness). We have also extended our calculations to explore and visualize the distinct behavior of charge distributions in coordinate space as well as charge densities in impact parameter space. Furthermore, magnetization density in impact parameter space has also been investigated. Quantitative as well as qualitative analysis of all the distributions has been carried out.
