Hypothetical long-lived massive colored particles ( MCPs or Y s ) would be confined in colorless exotic strongly interacting massive particles ( SIMPs ) at color confinement temperature of T _ { C } \sim 200 MeV .
Two long-lived MCPs form a bound state ( Y \bar { Y } ) at collisions of two SIMPs .
We study sensitivities of MCP annihilation to decay properties of resonances ( Y \bar { Y } ) , and binding energies or energy levels of exotic SIMPs .
The ( Y \bar { Y } ) formation is assumed to dominantly proceed through resonances of ( Y \bar { Y } ) in this paper .
We make a toy model of the effective cross section for Y \bar { Y } annihilation .
Abundances of SIMPs are then calculated for different sets of parameters specifying properties of ( Y \bar { Y } ) resonances , binding energies of SIMPs , the initial abundance and the mass of MCP .
Calculated relic abundances for respective SIMP species are 2 \times 10 ^ { -8 } – 3 \times 10 ^ { -4 } times that of baryon .
They can be much higher but can not be much smaller than the previous estimate .
The abundances can be consistent depending on parameters with the possible scenario that SIMPs bind to nuclei and subsequent exotic nuclear reactions reduce the primordial abundance of ^ { 7 } Li or enhance those of ^ { 9 } Be and/or B in the early Universe .
A unique information on the quark-hadron phase transition in the early Universe may become available in future by elaborated studies on the annihilation process with light element abundances as observables .
