    Nonextensive Nambu Jona-Lasinio model of QCD matter revisited

    Jacek Rozynek🇵🇱 · Grzegorz Wilk🇵🇱

    We present a revisited version of the nonextensive QCD-based Nambu - Jona-Lasinio (NJL) model describing the behavior of strongly interacting matter proposed by us some time ago. As before, it is based on the nonextensive generalization of the Boltzmann-Gibbs (BG) statistical mechanics used in the NJL model to its nonextensive version based on Tsallis statistics, but this time it fulfils the basic requirements of thermodynamical consistency. Different ways in which this can be done, connected with different possible choices of the form of the corresponding nonextensive entropies, are presented and discussed in detail. The corresponding results are compared, discussed and confronted with previous findings.

    Electromagnetic Transition Strengths for Light Nuclei in the Skyrme model

    M. Haberichter🇬🇧 · P.H.C. Lau🇯🇵 · N.S. Manton🇬🇧

    We calculate reduced electromagnetic transition strengths for light nuclei of mass numbers and within the Skyrme model. We find that the predicted transition strengths are of the correct order of magnitude and the computed intrinsic quadrupole moments match the experimentally observed effective nuclear shapes. For the Hoyle state we predict a large value of . For Oxygen-16, we can obtain a quantitative understanding of the ground state rotational band and the rotational excitations of the second spin-0 state, .
