Using the method of few-body physics, we obtain the relation between the correlation energies of the low-lying states of the positively charged exciton X+ and the radius of quantum dots. We also calculate the binding energies of the ground state of a positively charged exciton as a function of the electron-to-hole mass ratio for a few values of the strength of the cofinement. We find that there exi
