New insights into the nature of the and resonances away from the SU(3) limit
Feng-Kun Guo, Yuki Kamiya, Maxim Mai +1
Starting from the SU(3) limit, we consider the nature of the dynamically generated resonances , and as the pion and kaon masses are tuned to their phys…
Inclusion of electroproduction data in a coupled channel analysis
M. Mai, J. Hergenrather, M. Döring +4
Exclusive electroproduction reactions provide an access to the structure of excited baryons. To extract electroproduction multipoles encoding this information, the Jülich-Bonn-Wash…
Nature of the and resonances via coupled-channel dynamics
Yu-Fei Wang, Ulf-G. Meißner, Deborah Rönchen +1
This work aims at determining the composition of certain and resonances, i.e. whether they are compact states formed directly by quarks and gluons, or hadronic molecules…
On the role of isospin violation in the pion-nucleon -term
Martin Hoferichter, Jacobo Ruiz de Elvira, Bastian Kubis +1
In recent years, a persistent tension between phenomenological and lattice QCD determinations of the pion-nucleon -term has developed. In particular, lattice-QCD calcul…
Floating block method for quantum Monte Carlo simulations
Avik Sarkar, Dean Lee, Ulf-G. Meißner
Quantum Monte Carlo simulations are powerful and versatile tools for the quantum many-body problem. In addition to the usual calculations of energies and eigenstate observables, qu…
Structure Factors for Hot Neutron Matter from Ab Initio Lattice Simulations with High-Fidelity Chiral Interactions
Yuan-Zhuo Ma, Zidu Lin, Bing-Nan Lu +6
We present the first ab initio lattice calculations of spin and density correlations in hot neutron matter using high-fidelity interactions at next-to-next-to-next-to-leading order…
