Light nuclei with semilocal momentum-space regularized chiral interactions up to third order
P. Maris, E. Epelbaum, R. J. Furnstahl +17
We present a systematic investigation of few-nucleon systems and light nuclei using the current LENPIC interactions comprising semilocal momentum-space regularized two- and three-n…
Hyperon electromagnetic form factors in the timelike region
Johann Haidenbauer, Ulf-G. Meißner, Ling-Yun Dai
Electromagnetic form factors of hyperons (, , ) in the timelike region, accessible in the reaction , are studied. The focus is on energies close to the…
Dyson-Schwinger approach to pion-nucleon scattering using time-ordered perturbation theory
B. Blankleider, J. L. Wray, A. N. Kvinikhidze
We present a simple description of pion-nucleon () scattering taking into account the full complexity of pion absorption and creation on the nucleon. To do this we solve Dyson-…
Hidden spin-isospin exchange symmetry
Dean Lee, Scott Bogner, B. Alex Brown +8
The strong interactions among nucleons have an approximate spin-isospin exchange symmetry that arises from the properties of quantum chromodynamics in the limit of many colors, $N_…
Towards the continuum coupling in nuclear lattice effective field theory I: A three-particle model
J. -J. Wu, Ulf-G. Meißner
Weakly bound states often occur in nuclear physics. To precisely understand their properties, the coupling to the continuum should be worked out explicitely. In a first step, we us…
Jacobi no-core shell model for -shell hypernuclei
Hoai Le, Johann Haidenbauer, Ulf-G. Meißner +1
We extend the recently developed Jacobi no-core shell model to hypernuclei. Based on the coefficients of fractional parentage for ordinary nuclei, we define a basis where the hyper…
Impurity Lattice Monte Carlo for Hypernuclei
Dillon Frame, Timo A. Lähde, Dean Lee +1
We consider the problem of including hyperons into the ab initio framework of nuclear lattice effective field theory. In order to avoid large sign oscillations in Monte Carlo s…
-factor and static quadrupole moment for the wobbling mode in La
Q. B. Chen, S. Frauendorf, N. Kaiser +2
The -factor and static quadrupole moment for the wobbling mode in the nuclide La are investigated as functions of the spin by employing the particle rotor model. The…
Subleading contributions to the nuclear scalar isoscalar currents
Hermann Krebs, Evgeny Epelbaum, Ulf-G. Meißner
We extend our recent analyses of the nuclear vector, axial-vector and pseudoscalar currents and derive the leading one-loop corrections to the two-nucleon scalar current operator i…
Static quadrupole moments of nuclear chiral doublet bands
Q. B. Chen, N. Kaiser, Ulf-G. Meißner +1
The static quadrupole moments (SQMs) of nuclear chiral doublet bands are investigated for the first time taking the particle-hole configuration $π(1h_{11/2}) \otimes ν(1h_{11/2})^{…
Hyperon-nuclear interactions from SU(3) chiral effective field theory
Stefan Petschauer, Johann Haidenbauer, Norbert Kaiser +2
The interaction between hyperons and nucleons has a wide range of applications in strangeness nuclear physics and is a topic of continuing great interest. These interactions are no…
Precision Predictions
Ulf-G. Meißner
Precision predictions combined with precise measurements are a major tool in sharpening our understanding of the fundamental laws underlying microscopic as well as macroscopic syst…
Effect of Nucleon Dressing on the Triton Binding Energy
B. Blankleider, S. S. Kumar, A. N. Kvinikhidze
The effect of nucleon dressing by pions, on the binding energy of three nucleons interacting via two-body forces, is calculated for the first time within a conventional nuclear phy…
Box diagram contribution to the axial two-nucleon current
Hermann Krebs, Evgeny Epelbaum, Ulf-G. Meißner
Recently, we have worked out the axial two-nucleon current operator to leading one-loop order in chiral effective field theory using the method of unitary transformation. Our final…
How to renormalize integral equations with singular potentials in effective field theory
E. Epelbaum, A. M. Gasparyan, J. Gegelia +2
We briefly review general concepts of renormalization in quantum field theory and discuss their application to solutions of integral equations with singular potentials in the few-n…
