Title: Possible f Quark Model of Tetraquarks and Pentaquarks
Abstract: Selected tetraquark and pentaquark candidates are compared to meson and baryon states populated by ~2.9 GeV/c2 f quarks postulated by Chapman. The meson and baryon states incorporating an f quark are modeled using a first-order mass formula based on the methodology developed by Zel'dovich and Sakharov. The resulting states have masses below the experimental tetraquark and pentaquark values. First-order mesons and baryons mass formula results containing an f quark improve as the mass of the postulated quark increases.
