In light of the recently observed resonance states PΟsΞβ(4338)0 and Pcsβ(4459)0 by LHCb Collaboration in
J/ΟΞ decay channel, we perform a systematical study of all possible
hidden-heavy pentaquarks with strangeness S=0,β1,β2,β3, in unified framework
of MIT bag model. The color-spin wavefunctions presented in terms of
Young-Yamanouchi bases and transformed into baryon-meson couplings, are
utilized to calculate masses, magnetic moments and ratios of partial widths.
With numerical analysis, the observed PΟsΞβ(4338)0 is likely
to be a 1/2β compact Pcsβ pentaquark, and Pcsβ(4459)0 favors
two-peak structure of 3/2β and 1/2βPcsβ states. Further predictions
on hadron properties and decay channels are given to compact Pcssβ,
Pcsssβ states and bottom sectors.Comment: 14 pages, 11 tables, 1 figure and two appendices, created by RevTex
