Perturbative application of next-to-leading order pionless EFT for nuclei in a finite volume
Tafat Weiss-Attia, Martin Schäfer, Betzalel Bazak
Lattice quantum chromodynamics (LQCD) calculations with physical pion mass would revolutionize nuclear physics by enabling predictions based on the fundamental theory of the strong…
Improved action for contact effective field theory
L. Contessi, M. Schäfer, U. van Kolck
We present an improved action for renormalizable effective field theories (EFTs) of systems near the two-body unitarity limit. The ordering of EFT interactions is constrained, but…
Five-body calculation of -wave -He scattering at next-to-leading order pionless effective field theory
Mirko Bagnarol, Martin Schäfer, Betzalel Bazak +1
We present the first five-body calculations of -wave -He scattering within leading order and next-to-leading order (NLO) pionless effective field theory. Using an harmoni…
Few nucleons scattering in pionless effective field theory
Martin Schäfer, Betzalel Bazak
We present a comprehensive theoretical study of low-energy few nucleon scattering for systems with . To this end, we utilize pionless effective field theory, which we empl…
Emergence of H resonance in contact theories
Lorenzo Contessi, Martin Schäfer, Johannes Kirscher +2
We obtain the - and -wave low-energy scattering parameters for nH elastic scattering and the position of the H resonance using the pionless effective field…
Consequences of increased hypertriton binding for -shell -hypernuclear systems
M. Schäfer, B. Bazak, N. Barnea +2
Consequences of increasing the binding energy of the hypertriton ground state from the emulsion value $B^{\rm EMUL}_Λ({_Λ^3}{\rm H}_{\rm g.s.})…
Eta-mesic nuclei
A. Cieply, J. Mares, M. Schaefer +4
In this contribution we report on theoretical studies of nuclear quasi-bound states in few- and many-body systems performed recently by the Jerusalem-Prague Collaboration [1-5]…
Onset of nuclear binding
Nir Barnea, Betzalel Bazak, Eliahu Friedman +4
Recent studies of nuclear quasibound states by the Jerusalem-Prague Collaboration are reviewed, focusing on stochastic variational method self consistent calculations of fe…
Electromagnetic Form Factor of the Nucleon in the Time-like Region
M. Schaefer, H. C. Doenges, U. Mosel
We explore the possibility to verify vector meson dominance for the nucleon by measuring the half-off-shell form factor in the vector-meson mass region. Cross sections for the proc…
Microscopic Model of the Time Like Electromagnetic Form Factor of the Nucleon
H. C. Doenges, M. Schaefer, U. Mosel
A microscopic model of the electromagnetic form factor of the nucleon is developed in a hadronic framework, including pions, nucleons and the Delta-resonance explicitly. The space…
Dilepton Production in Nucleon-Nucleon Interactions
M. Schäfer, H. C. Dönges, A. Engel +1
Starting from a realistic one--boson--exchange--model fitted to the amplitudes of elastic nucleon--nucleon scattering and the process we perform a fully relativi…
Pion-nucleus reactions in a microscopic transport model
A. Engel, W. Cassing, U. Mosel +2
We analyse pion-nucleus reactions in a microscopic transport model of the BUU type, which propagates nucleons, pions, deltas and N(1440)-resonances explicitly in space and time. In…
