We present a brief review of some topical issues in the study of QCD exotic hadrons. A special emphasis of the threshold phenomena is made by taking into account the implementation of the effective field theory study of hadronic molecules and the impact arising from the triangle singularity. A combined analysis may provide some clues towards a better understanding of the hadron spectroscopy.

The gravitational waves emitted from a binary neutron star merger, as predicted from general relativistic magneto-hydrodynamics calculations, are sensitive to the appearance of quark matter and the stiffness of the equation of state of QCD matter present in the inner cores of the stars. These astrophysically created extremes of thermodynamics do match, to within 20%, the values of densities and temperatures which are found in relativistic heavy ion collisions, if though at quite different rapidity windows, impact parameters and bombarding energies of the heavy nuclear systems. In this article we combine the results obtained in general relativistic simulations of binary neutron star systems with ones from heavy ion collisions in the lab to pin down the EOS and the phase structure of dense matter. We discuss that the postmerger gravitational wave emission of the neutron star merger remnant might give, in the near future, insides about the properties of the hadron quark transition.

An independent theoretical analysis is presented for the 2 band in 248Cf, which has been identified to spin $25{\hbar}$ and excitation energy $\geqslant$4 MeV, implying the fission barrier persists at least up to that angular momentum and excitation for the configuration. The underlying physics for the experimentally observed band is discussed in terms of alignment properties and decay pattern. Different scenarios for assumptions about intrinsic configuration are assessed with transition rates analysis. It turns out that only by invoking a particle-phonon mixing picture can the decay characteristics of the pair of bands be well accounted for, i.e. quasiparticle nature forbids decay to ground-state band, non-axial octupole phonon shifts the signature partners in energy and diminishes mutual interaction. The coexisting normal and superconducting phases are tentatively attributed to weak neutron pairing in the proximity of 152 deformed shell gap.

We apply the coupled-channel Gamow shell model to calculate the spectra of 17O and 17F, as well as 16O(p,p) elastic cross sections at low energies. It is shown that continuum coupling is necessary to account for the particle-emission width of the unbound eigenstates of 17O and 17F. The low-lying spectrum of 17O and 17F and 16O(p,p) excitations functions are in fair agreement with experimental data. Nevertheless, it is also shown that the use of a realistic nuclear Hamiltonian is needed to have an optimal reproduction of 16O(p,p) elastic cross sections in the low-energy region.

With the application of the notch technique, the radial sensitive regions for the tightly bound system 16O+208Pb, and weakly bound system 9Be+208Pb were investigated. It is the first time that the shape and resonant scattering can be identified from the sensitivity functions. Moreover, strong energy dependence of sensitive regions were found for both the tightly and stable weakly bound systems: in the above barrier region, the sensitive region varies around the strong absorption radius; while below the barrier, the behavior of sensitive region is close to that of the closest approach in the Coulomb field.

ANAETF, a large data analysis framework for the External Target Facility (ETF) of HIRFL-CSR, has been developed and successfully used for data analysis in radioactive ion beam experiments. This paper covers the flow of data processing in the program, the general tracking algorithm for the drift chambers, the particle identification (PID) approach, and the techniques for extraction of reaction cross sections. The program achieves total detecting efficiencies of around ~90% and gives clear PID spectrum for carbon and beryllium fragments produced from the reaction of 240 MeV/u 12C secondary beams on a carbon target. The obtained cross sections are consistent with the previously reported experimental results.
