Hypothetical long-lived massive colored particles (MCPs or Ys) would beconfined in colorless exotic strongly interacting massive particles (SIMPs) atcolor confinement temperature of T_C /sim 200 MeV. Two long-lived MCPs form abound state (Y /bar{Y}) at collisions of two SIMPs. We study sensitivities ofMCP annihilation to decay properties of resonances (Y /bar{Y}), and bindingenergies or energy levels of exotic SIMPs. The (Y /bar{Y}) formation is assumedto dominantly proceeds through resonances of (Y/bar{Y}) in this paper. We makea toy model of the effective cross section for Y /bar{Y} annihilation.Abundances of SIMPs are then calculated for different sets of parametersspecifying properties of (Y /bar{Y}) resonances, binding energies of SIMPs, theinitial abundance and the mass of MCP. Calculated relic abundances forrespective SIMP species are 2 x 10^{-8}--3 x 10^{-4} times that of baryon. Theycan be much higher but cannot be much smaller than the previous estimate. Theabundances can be consistent depending on parameters with the possible scenariothat SIMPs bind to nuclei and subsequent exotic nuclear reactions reduce theprimordial abundance of 7Li or enhance those of 9Be and/or B in the earlyuniverse. A unique information on the quark-hadron phase transition in theearly universe may become available in future by elaborated studies on theannihilation process with light element abundances as observables.
