38. Baryonic forces in SU(3) chiral effective field theory

Stefan Petschauer (TU München)

Section F: Nuclear and Astroparticle Physics

We use SU(3) chiral effective field theory to describe the two- and three-baryon forces. Results for the hyperon-nucleon interaction at next-to-leading order are reported. These potentials include one- and two-meson exchange diagrams as well as contact terms with SU(3) symmetric low-energy constants. Furthermore we present potentials for the leading order three-baryon interactions, which...

47. Chiral effective field theory for light nuclei

Evgeny Epelbaum (University of Bochum)

Section F: Nuclear and Astroparticle Physics

I review recent progress in the application of chiral effective field theory to nuclear forces and low-energy nuclear observables. Both the continuum and the lattice formulations will be addressed.

86. Hadron interactions and exotic hadrons on the lattice

Yoichi Ikeda (RIKEN)

Section F: Nuclear and Astroparticle Physics

One of the interesting subjects in hadron physics is to look for the multiquark configurations. One of candidates is the H-dibaryon (udsuds), and the possibility of the bound H-dibaryon has been recently studied from lattice QCD. We also extend the HAL QCD method to define potential on the lattice between baryons to meson-meson systems including charm quarks to search for the bound tetraquark...

24. Relating the strangeness content of the nucleon with the mass shift of the phi meson in nuclear matter

Philipp Gubler (RIKEN)

Section F: Nuclear and Astroparticle Physics

The behavior of the $\phi$ meson at finite density is studied, making use of a QCD sum rule approach in combination with the maximum entropy method. It is demonstrated that a possible mass shift of the $\phi$ in nuclear matter is strongly correlated to the strangeness content of the nucleon, which is proportional to the strange sigma term, $\sigma_{sN}$. In contrast to earlier studies, our...

18. Strangeness in the nuclear medium: experimental studies with the KLOE Drift Chamber.

Oton Vazquez Doce (Excellence Cluster Universe, TU-Munich.)

Section F: Nuclear and Astroparticle Physics

The hyperon-pion and hyperon-nucleon(s) correlations following K- nuclear absorption in Helium and Carbon were investigated with the KLOE drift chamber and the results will be presented. To this end, KLOE [1] data (from 2004-2005) was analyzed using the detector itself as an active target. Also results from a more recent run (end of 2012) with a dedicated solid Carbon target will be...
