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...
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.
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

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...
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...
Challenges for Modeling Nuclear Structure: Are the Proton and Neutron Masses and A-body Interactions Relevant?
Modeling Nuclear Structure A-body Interactions Relevant
2011/1/7
We discuss some of the challenges that future nuclear modeling may face in order to improve the description of the nuclear structure. One challenge is related to the need for A-body nuclear interactio...

Dark Atoms of the Universe: towards OHe nuclear physics
Dark Atoms Universe OHe nuclear physics
2011/1/10
The nonbaryonic dark matter of the Universe is assumed to consist of new stable particles. A specific case is possible, when new stable particles bear ordinary electric charge and bind in heavy ”atoms...

The TRIGA IPR-R1 nuclear reactor at the Centro de Desenvolvimento da Tecnologia Nuclear CDTN/CNEN, Belo Horizonte, Brazil, has three irradiation facilities: a rotary specimen rack outside the reactor ...
Limiting soft particle emission in e+e-, hadronic and nuclear collisions
particle emission hadronic e+e- nuclear collisions
2010/3/16
In e+e- collisions the particle spectra at low momenta reflect the properties of the underlying "soft" QCD gluon bremsstrahlung: the particle density, in the limit p\to 0, becomes independent of the i...
