Resonance states in the $$Y_cN$$ potential model

Maeda, Saori*; Oka, Makoto  ; Liu, Y.-R.*

We calculate two-body $$J^{pi}=0^{+}, 1^{+}$$, and $$J^{pi}=2^{+}$$ resonance states of $$Y_{c}$$ ($$= Lambda_{c}$$, $$Sigma_{c}$$, or $$Sigma_{c}^{*}$$) and $$N$$ using the complex scaling method. We employ the $$Y_{c}N$$-CTNN potentials, which were proposed in our previous study, and obtain four resonances near $$Sigma_{c}N$$ and $$Sigma_{c}^{*}N$$ thresholds. From the analysis by the binding energies of partial channel systems, we conclude that these resonance states are Feshbach resonances. We compare the results with the $$Y_{c}N$$ resonance states in the heavy quark limit, where the $$Sigma_{c}N$$ and $$Sigma_{c}^{*}N$$ thresholds are degenerate, and find that they form two pairs of the heavy-quark doublets in agreement with the heavy quark spin symmetry.
