摘要：

We have found a mistake in the code in the numerical calculation. As a result, the γ factor needs to be chosen at about 4.0 so that the mass spectrum of all the observed first excited P-wave charmonium states can be reproduced well simultaneously in our scheme. In fact, since the wave functions we used in our paper are not the same as the ones in the ordinary QPC model, we do not need to choose the γ parameter to be the same as in [1,2]. The mass spectrum for the states does not change much. The corrected results are shown in Table I which replaces the original Table I in [3]. The other numerical results to be corrected are as follows: (Formula Presented). © 2017 American Physical Society.
