Constraints on the threshold K- nuclear potential from FINUDA (stopped K-, pi-) hypernuclear spectra
hypernuclei kaon-induced reactions mesonic atoms
2011/1/6
1s hypernuclear formation rates in stopped K− reactions on several p-shell targets are derived from hypernuclear formation spectra measured recently by the FINUDA Collaboration and are compared...
Analysis of three-nucleon forces effects in the $A=3$ system
Analysis of three-nucleon forces effects $A=3$ system
2011/1/6
Using modern nucleon-nucleon interactions in the description of the A = 3, 4 nuclear systems the 2 per datum results to be much bigger than one. In particular it is not possible to reproduce the thre...
These are personal recollections of how Gerry Brown’s work and thinking influenced the development of the chiral effective Lagrangian based theory of nuclear forces.
The experimental data of the COSY-GEM collaboration for the recoil-free transfer reaction p(27Al,3He)π−p′X, leading to the formation of bound state of eta (η) meson in 25Mg nucleus, is reanalyze...
In this paper, we briefly introduce the interests and the recent research activities on the η mesic nuclei. We also mention the activities on the η′(958) mesic nucleus formation .
The nuclear states of K and are bound by a similar mechanism -the excitations of nucleons to Λ(1405) and N(1535) resonant states. The observed large differences in binding energies are understood i...

Strangeness nucleon mixed action calculation
2011/1/14
The contributions of strange quarks to the nucleon mass and the nucleon spin are investigated in a mixed action scheme employing domain wall valence quarks and quark loops on MILC asqtad

Recent progress on nuclear potentials from lattice QCD
Recent progress nuclear potentials lattice QCD
2011/1/14
A new method for nuclear potentials is reviewed. The strategy to extract the potential from the
Nambu-Bethe-Salpeter wave function in lattice QCD is explained and the first result based on the method...
Mixture of Tonks-Girardeau gas and Fermi gas in one-dimensional optical lattices
Mixture of Tonks-Girardeau gas Fermi gas one-dimensional optical lattices
2010/11/25
We study the Bose-Fermi mixture with infinitely boson-boson repulsion and finite boson-Fermion
repulsion. By using a generalized Jordan-Wigner transformation, we show that the system can be
mapped t...
Shell-model calculations that include both and configurations with p-shell cores are used to interpret -ray transitions in 7 Li, 9 Be, 10 B, 11 B, 12 C, 15 N, and 16 O observed with the Hy...
Density-dependent nuclear interactions and the beta decay of 14C: chiral three-nucleon forces and Brown-Rho scaling
Effective field theory at finite density chiral three-nucleon force Brown-Rho scaling
2011/1/7
We study the role of density-dependent low-momentum nucleon-nucleon interactions in describing the anomalously long beta decay lifetime of 14C. We approach this problem both from the perspective of ch...
Gradient Catastrophe and Fermi Edge Resonances in Fermi Gas
Gradient Catastrophe Fermi Edge Resonances Fermi Gas
2010/11/19
A smooth spatial disturbance of the Fermi surface in a Fermi gas inevitably becomes sharp. This
phenomenon, called the gradient catastrophe, causes the breakdown of a Fermi sea to disconnected parts ...
Nuclear energy functional with a surface-peaked effective mass: Global properties
Nuclear energy functional surface-peaked effective mass: Global properties
2011/1/7
A correction to the nuclear functional is proposed in order to improve the density of states around the Fermi surface. The induced effect of this correction is to produce a surface-peaked effective ma...
Comment on "Five-Body Cluster Structure of the Double-Lambda Hypernucleus Lambda-Lambda-11Be"
Five-Body Cluster Structure Double-Lambda Hypernucleus Lambda-Lambda-11Be
2011/1/6
Hiyama et al. [1] have recently reported on a pioneering five-body n cluster-model (CM)
calculation of 11 Be in order to confront a possible interpretation of the KEK-E373 HIDA event [2].
