Decay widths of $$^3 P_J$$ 3 P J charmonium to $$DD,DD^*,D^*D^*$$ D D , D D ∗ , D ∗ D ∗ and corresponding mass shifts of $$^3 P_J$$ 3 P J charmonium
Abstract In this work, we calculate the amplitudes of the processes $$c{{\bar{c}}}({^3P_J}) \rightarrow DD,DD^*, D^*D^* \rightarrow c\bar{c}({^3P_J})$$ c c ¯ ( 3 P J ) → D D , D D ∗ , D ∗ D ∗ → c c ¯ ( 3 P J ) in the leading order of the nonrelativistic expansion. The imaginary parts of the amplitud...
