The complex scaling method (CSM) is one of the most powerful methods of describing the resonances with complex energy eigenstates, based on non-Hermitian quantum mechanics. We present the basic application of CSM to the properties of the unbound phenomena of light nuclei. In particular, we focus on many-body resonant and non-resonant continuum states observed in unstable nuclei. We also investigate the continuum level density (CLD) in the scattering problem in terms of the Green's function with CSM. We discuss the explicit effects of resonant and non-resonant contributions in CLD and transition strength functions.

  1. Quarkoniumlike states above open-flavor thresholds in Born-Oppenheimer EFT

    hep-ph 2026-08 conditional novelty 6.0 of 10

    A QCD-constrained Born-Oppenheimer calculation organizes most observed quarkoniumlike states above open-flavor thresholds into heavy-quark-spin-symmetry multiplets and predicts a shallow X_b.

  2. Possible $\bar{D}^{(*)} \Xi_{cc}^{(*)}$ and $\Xi_{cc}^{(*)}\Xi_{cc}^{(*)}$ molecules as superflavor partners of $T_{cc}$

    hep-ph 2026-03 conditional novelty 6.0 of 10

    Using one-boson-exchange potentials and superflavor symmetry, the authors predict many hadronic molecules of charmed mesons and doubly charmed baryons as partners of the Tcc tetraquark.

  3. Perturbative calculations of nucleon-deuteron elastic scattering in chiral effective field theory

    nucl-th 2026-02 conditional novelty 6.0 of 10

    A fixed-kernel perturbation framework computes nucleon-deuteron scattering up to next-to-leading order in chiral EFT, benchmarked against wave-packet continuum discretization.
