Erratum to: Eur. Phys. J. C (2022) 82:882 https://doi.org/10.1140/epjc/s10052-022-10850-8

In the paper [1], in the numerical evaluation, the value of \(G'\) after Eq. (4) was taken as \(G'=\frac{3g'}{4\pi ^2f}\) instead of \(G'=\frac{3g'^2}{4\pi ^2f}\). Nothing changes in the paper about the states obtained and their masses. Only the widths of the last two states of Table 1 change, (the last two cells of the last column). We show below the table with the correct results. The conclusions of the paper remain unchanged.
