| : \small Invariant-mass distribution of the $\Ocstst$ candidates in (a) data set 1 and (b) data set 2, with the fit results overlaid. A bin width of 5\mev is used for plotting. The previously observed excited $\Oc$ states are shown in blue dashed lines. The $\OcX{3185}$ state is shown in the brown area, and the $\OcX{3327}$ state is shown in the red area. Three feed-down components are shown as the yellow areas, while the green long-dashed line corresponds to the combinatorial background. |
