摘要
The color-flavor locked(CFL) strangelets have been investigated in a new quark model with linear confinement and one-gluon-exchange interactions.Considering Coulomb energy,we have studied the properties of three kinds of CFL strangelets,namely,positively charged,negatively charged and nearly neutral CFL strangelets.It is found that the one-gluon-exchange effect lowers the energy of a strangelet considerably and thus makes it much more stable than without considering the effect.The charge of a positive strangelet is larger than 0.15A 2/3 with A being the baryon number,but smaller than that in bag model.The charge of a negatively charged or nearly neutral CFL strangelet is nearly proportional to A 1/3.
