    Predictions for isobaric collisions at = 200 GeV from a multiphase transport model

    Wei-Tian Deng🇨🇳 · Xu-Guang Huang🇨🇳 · Guo-Liang Ma🇨🇳 · Gang Wang🇺🇸

    The isobaric collisions of Ru + Ru and Zr + Zr have recently been proposed to discern the charge separation signal of the chiral magnetic effect (CME). In this article, we employ the string melting version of a multiphase transport model to predict various charged-particle observables, including , spectra, elliptic flow (), and particularly possible CME signals in Ru + Ru and Zr + Zr collisions at = 200 GeV. Two sets of the nuclear structure parametrization have been explored, and the difference between the two isobaric collisions appears to be small, in terms of , spectra, and for charged particles. We mimic the CME by introducing an initial charge separation that is proportional to the magnetic field produced in the collision, and study how the final-state interactions affect the CME observables. The relative difference in the CME signal between the two isobaric collisions is found to be robust, insensitive to the final-state interactions.

    Structure of even-even Cadmium isotopes from the beyond-mean-field interacting boson model

    K. Nomura · J. Jolie

    The structure of even-even Cd isotopes is investigated based on the self-consistent mean-field approach. By mapping the quadrupole- deformation energy surface, obtained from the constrained self-consistent mean-field calculations with a choice of the Skyrme force and pairing property, onto the Hamiltonian of the interacting boson model with configuration mixing, the strength parameters of the Hamiltonian are determined. The low-lying excitation spectra and electric quadrupole transition rates for the considered Cd nuclei are computed by the resultant Hamiltonian, and are compared in detail with the experimental data. Our semi-microscopic prediction identifies several intruder states as suggested empirically, and overall, provides a reasonable qualitative description of the experimental energy levels and transition rates.
