Description

In a previous paper by Park and Rho, an SU(3)f chiral bag or chiral hyperbag was constructed and studied in detail, with a focus on the Cheshire Cat structure of the hyperons. This paper supplies some of the details left out in that paper, i.e., calculational procedure of vacuum contributions, their divergence structure and subtraction procedure to the inertia parameters that figure in the hyperons. We calculate them numerically by means of eigenmode sums including all the quark eigenstates up to vertical strokeERvertical stroke=250. We are able to isolate the leading divergences, in particular, their chiral-angle dependences, and consequently make subtractions to make the inertia parameters finite and consistent, in a manner quite analogous to the SU(2)f case.
