Kaonic deuterium and low-energy antikaon-nucleon interaction

Wataru Horiuchi, Tetsuo Hyodo, Wolfram Weise

A new evaluation of the level shift and width of kaonic deuterium is presented based on an accurate three-body calculation, using as input a realistic antikaon-nuc…

Tensor Fermi liquid parameters in nuclear matter from chiral effective field theory

J. W. Holt, N. Kaiser, T. R. Whitehead

We compute from chiral two- and three-body forces the complete quasiparticle interaction in symmetric nuclear matter up to twice nuclear matter saturation density. Second-order per…

Effect of the QCD equation of state and strange hadronic resonances on multiparticle correlations in heavy ion collisions

Paolo Alba, Valentina Mantovani Sarti, Jorge Noronha +4

The QCD equation of state at zero baryon chemical potential is the only element of the standard dynamical framework to describe heavy ion collisions that can be directly determined…

Green's function method for the single-particle resonances in a deformed Dirac equation

T. -T. Sun, L. Qian, C. Chen +2

Single-particle resonances are crucial for exotic nuclei near and beyond the drip lines. Since the majority of nuclei are deformed, the interplay between deformation and orbital st…

Effects of tensor forces in nuclear spin-orbit splittings from ab initio calculations

Shihang Shen, Haozhao Liang, Jie Meng +2

A systematic and specific pattern due to the effects of the tensor forces is found in the evolution of spin-orbit splittings in neutron drops. This result is obtained from relativi…

Scattering of decuplet baryons in chiral effective field theory

J. Haidenbauer, S. Petschauer, N. Kaiser +2

A formalism for treating the scattering of decuplet baryons in chiral effective field theory is developed. The minimal Lagrangian and potentials in leading-order SU(3) chiral effec…

Effective field theory for triaxially deformed nuclei

Q. B. Chen, N. Kaiser, Ulf-G. Meißner +1

Effective field theory (EFT) is generalized to investigate the rotational motion of triaxially deformed even-even nuclei. A Hamiltonian, called the triaxial rotor model (TRM), is o…

Parity partners in the baryon resonance spectrum

Ya Lu, Chen Chen, Craig D. Roberts +3

We describe a calculation of the spectrum of flavour-SU(3) octet and decuplet baryons, their parity partners, and the radial excitations of these systems, made using a symmetry-pre…

Constraining the interaction from the level shift of kaonic deuterium

Tsubasa Hoshino, Shota Ohnishi, Wataru Horiuchi +2

Motivated by the precise measurement of the level shift of kaonic hydrogen, we perform accurate three-body calculations for the spectrum of kaonic deuterium using a realistic…

Fully self-consistent relativistic Brueckner-Hartree-Fock theory for finite nuclei

Shihang Shen, Haozhao Liang, Jie Meng +2

Starting from the relativistic form of the Bonn potential as a bare nucleon-nucleon interaction, the full Relativistic Brueckner-Hartree-Fock (RBHF) equations are solved for finite…

Assessing theoretical uncertainties in fission barriers of superheavy nuclei

S. E. Agbemava, A. V. Afanasjev, D. Ray +1

Theoretical uncertainties in the predictions of inner fission barrier heights in superheavy elements have been investigated in a systematic way for a set of state-of-the-art covari…

Third-order particle-hole ring diagrams with contact-interactions and one-pion exchange

N. Kaiser

The third-order particle-hole ring diagrams are evaluated for a NN-contact interaction of the Skyrme type. The pertinent four-loop coefficients in the energy per particle $\bar E(k…

Nuclear matrix element of neutrinoless double- decay: Relativity and short-range correlations

L. S. Song, J. M. Yao, P. Ring +1

Background: The discovery of neutrinoless double-beta () decay would demonstrate the nature of neutrinos, have profound implications for our understanding of matter-antimatte…

Meson-baryon scattering to one-loop order in heavy baryon chiral perturbation theory

Bo-Lin Huang, Jin-Sheng Zhang, Yun-De Li +1

We calculate the T-matrices of pseudoscalar meson octet-baryon scattering to one-loop order in SU(3) heavy baryon chiral perturbation theory. The pertinent combinations of low-ener…
