Coupled-channel analysis of pion- and eta-electroproduction with the Jülich-Bonn-Washington model
Maxim Mai, Michael Döring, Carlos Granados +6
Pion and eta electroproduction data are jointly analyzed for the first time, up to a center-of-mass energy of 1.6 GeV. The framework is a dynamical coupled-channel model, based on…
Perturbative quantum Monte Carlo method for nuclear physics
Bing-Nan Lu, Ning Li, Serdar Elhatisari +3
While first order perturbation theory is routinely used in quantum Monte Carlo (QMC) calculations, higher-order terms present significant numerical challenges. We present a new app…
Three-body renormalization group limit cycles based on unsupervised feature learning
Bastian Kaspschak, Ulf-G. Meißner
Both the three-body system and the inverse square potential carry a special significance in the study of renormalization group limit cycles. In this work, we pursue an exploratory…
hypernuclei based on interactions from chiral effective field theory
Hoai Le, Johann Haidenbauer, Ulf-G. Meißner +1
We investigate the existence of bound \break states in systems with baryons using the Jacobi NCSM approach in combination with chiral NN and N interactions. We find…
Exploring the interaction by measurements of the correlation function
J. Haidenbauer, U. -G. Meißner
The spin-dependent components of the fundamental hyperon-nucleon interactions are largely unknown. We show that under reasonable assumptions, a measurement of the correlati…
Constraints on the -neutron interaction from charge symmetry breaking in the -- hypernuclei
Johann Haidenbauer, Ulf-G. Meißner, Andreas Nogga
We utilize the experimentally known difference of the separation energies of the mirror hypernuclei and to constrain the -neutron interaction. W…
Wigner SU(4) symmetry, clustering, and the spectrum of C
Shihang Shen, Timo A. Lähde, Dean Lee +1
We present lattice calculations of the low-lying spectrum of C using a simple nucleon-nucleon interaction that is independent of spin and isospin and therefore invariant und…
On the structure in the cross section at the threshold
J. Haidenbauer, U. -G. Meißner
The complexity of threshold phenomena is exemplified on a prominent and long-known case - the structure in the cross section (invariant mass spectrum) at the opening of the $Σ…
Jülich-Bonn-Washington Model for Pion Electroproduction Multipoles
Maxim Mai, Michael Döring, Carlos Granados +5
Pion electroproduction off the proton is analyzed in a new framework based on a general parametrization of transition amplitudes, including constraints from gauge invariance and th…
Effective field theory for shallow P-wave states
E. Epelbaum, J. Gegelia, H. P. Huesmann +2
We discuss the formulation of a non-relativistic effective field theory for two-body P-wave scattering in the presence of shallow states and critically address various approaches t…
-factor and static quadrupole moment of Pr, Pd, and Au in wobbling motion
C. Broocks, Q. B. Chen, N. Kaiser +1
The -factor and static quadrupole moment of the nuclides Pr, Pd, and Au in the wobbling motion are investigated in the particle-rotor model as functions…
S-shell hypernuclei based on chiral interactions
Hoai Le, Johann Haidenbauer, Ulf-G Meißner +1
We generalize the Jacobi no-core shell model (J-NCSM) to study double-strangeness hypernuclei. All particle conversions in the strangeness sectors are explicitly taken in…
