    Comparaison between Coulomb and Hulthèn potentials within Bohr Hamiltonian for -rigid nuclei in the presence of minimal length

    M. Chabab · A. El Batoul · M. Hamzavi · A. Lahbas · I. Moumene · M. Oulne

    In this work we solve the Schrödinger equation for Bohr Hamiltonian with Coulomb and Hulthén potentials within the formalism of minimal length in order to obtain analytical expressions for the energy eigenvalues and eigenfunctions by means of asymptotic iteration method. The obtained formulas of the energy spectrum and wave functions, are used to calculate excitation energies and transition rates of -rigid nuclei and compared with the experimental data at the shape phase critical point X(3) in nuclei.

    Lattice QCD Study of the Nucleon-Charmonium Interaction

    Takuya Sugiura🇯🇵 · Yoichi Ikeda🇯🇵 · Noriyoshi Ishii🇯🇵

    The -nucleon interaction is studied by lattice QCD calculations. At the leading order of the derivative expansion, the interaction consists of four terms: the central, the spin-spin, and two types of tensor forces. We determine these spin-dependent forces quantitatively by using the time-dependent HAL QCD method. We find that the spin-spin force is the main cause of the hyperfine splitting between the and the states, while the two tensor forces have much smaller effects on the S-wave scattering processes.

    Dense Baryonic Matter and Strangeness in Neutron Stars

    Wolfram Weise🇩🇪

    Recent developments of chiral effective field theory (ChEFT) applications to nuclear and neutron matter are summarized, with special emphasis on a (non-perturbative) extension using functional renormalisation group methods. Topics include: nuclear thermodynamics, extrapolations to dense baryonic matter and constraints from neutron star observables. Hyperon-nuclear interactions derived from SU(3) will be discussed with reference to the "hyperon puzzle" in neutron star matter.
