Author(s): F. Q. Chen (陈芳祁), Q. B. Chen (陈启博), Y. A. Luo (罗延安), J. Meng (孟杰), and S. Q. Zhang (张双全)

The pairing-plus-quadrupole Hamiltonian is diagonalized in a symmetry-restored basis, i.e., the triaxial quasiparticle states with angular momentum and particle number projections, and applied for chiral doublet bands in $^{128}\mathrm{Cs}$. The observed energy spectra and electromagnetic transition...

Analyzing the Fierz rearrangement freedom for local chiral two-nucleon potentials

2017-11-20T10:00:00+00:00

Author(s): L. Huth, I. Tews, J. E. Lynn, and A. Schwenk

Chiral effective field theory is a framework to derive systematic nuclear interactions. It is based on the symmetries of quantum chromodynamics and includes long-range pion physics explicitly, while shorter-range physics is expanded in a general operator basis. The number of low-energy couplings at ...

Author(s): S. N. More, S. K. Bogner, and R. J. Furnstahl

Background: Isolating nuclear structure properties from knock-out reactions in a process-independent manner requires a controlled factorization, which is always to some degree scale and scheme dependent. Understanding this dependence is important for robust extractions from experiment, to correctly ...

Estimates and power counting in uniform nuclear matter with softened interactions

Author(s): A. Dyhdalo, S. K. Bogner, and R. J. Furnstahl

Modern softened nucleon-nucleon interactions are well suited for perturbative many-body calculations, but a many-body power counting scheme is lacking. Estimates of diagrammatic contributions at finite density are important ingredients in such a scheme. Here we show how to make quantitative estimate...

We investigate the $^{26}\mathrm{O}$ unbound nucleus in a $^{24}\mathrm{O}+n+n$ three-body model. We use the hyperspherical formalism, which relies only on $^{24}\mathrm{O}+n$ and $n+n$ interactions. As $^{26}\mathrm{O}$ is unbound, even in its ground state, the long-range behavior of the wave funct...

Author(s): J. Kristiano, S. Clymton, and T. Mart

We propose the use of a pure spin-3/2 propagator in the $(3/2,0)⊕(0,3/2)$ representation in particle and nuclear physics. To formulate the propagator in a covariant form we use the antisymmetric tensor spinor representation and we consider the $\mathrm{Δ}$ resonance contribution to the elastic $πN$ ...

Author(s): Jinniu Hu and Hong Shen

The single-${\mathrm{Ξ}}^{−}$ hypernuclei are studied using a quark mean-field model. At the quark level, the ${\mathrm{Ξ}}^{−}$ hyperon is composed of one $d$ quark and two $s$ quarks, which are confined by the harmonic oscillator potentials. In the case of hadrons, the baryons interact with each o...

Ferreira, F. Krmpotić, C. A. Barbero, and A. R. Samana The one-quasiparticle random-phase approximation (one-QRPA) method is used to describe simultaneously both double-$β$-decay modes, giving special attention to the partial restoration of spin-isospin$\text{SU}(4)$symmetry. To implement this restoration and to fix the model parameters, we resort to ... [Phys. Rev.

We have incorporated the spin-dependent nucleon-nucleon cross sections into a Boltzmann-Uehling-Uhlenbeck transport model for the first time, using the spin-singlet and spin-triplet nucleon-nucleon elastic scattering cross sections extracted from the phase-shift analyses of nucleon-nucleon scatterin...

Flow harmonics from self-consistent particlization of a viscous fluid

Author(s): Zack Wolff and Denes Molnar

The quantitative extraction of quark-gluon plasma (QGP) properties from heavy-ion data, such as its specific shear viscosity $η/s$, typically requires comparison to viscous hydrodynamic or “hybrid” hydrodynamics + transport simulations. In either case, one has to convert the fluid to hadrons, yet wi...

We compare phenomenological results from $3+1\mathrm{D}$ quasiparticle anisotropic hydrodynamics (aHydroQP) with experimental data collected in the CERN Large Hadron Collider 2.76 TeV Pb-Pb collisions. In particular, we present comparisons of particle spectra, average transverse momentum, elliptic f...

Author(s): L. E. Finch and S. J. Murray

We propose the measurement of net $\mathrm{Λ}$ and $\overline{\mathrm{Λ}}$ helicity, correlated event by event with the magnitude and sign of charge separation along the event's magnetic field direction, as a probe to investigate the chiral magnetic effect (CME) in heavy-ion collisions. With a simpl...

Author(s): F. Didierjean et al.

Background: While the $N=50$ shell-gap evolution towards $^{78}\mathrm{Ni}$ is presently in the focus of nuclear structure research, experimental information on the neutron effective single-particle energy sequence above the $^{78}\mathrm{Ni}$ core remain scarce. Direct nucleon-exchange reactions ar...

We study the equation of state of QCD using an improved version of the three-flavor Polyakov–Nambu–Jona-Lasinio model beyond the mean-field approximation.
