Mini-Proceedings of ECT Workshop "Strangeness in Nuclei"
This workshop brought together international experts in the research area of
strangeness in nuclei physics, working on theory as well as on experiments, to
discuss the present status, to develop new methods of analysis and to have the
opportunity for brainstorming towards future studies, going towards a deeper
understanding of the hot topics in the low-energy QCD in the strangeness
sector
From Solar Proton Burning to Pionic Deuterium through the Nambu-Jona-Lasinio model of light nuclei
Within the Nambu-Jona-Lasinio model of light nuclei (the NNJL model),
describing strong low-energy nuclear interactions, we compute the width of the
energy level of the ground state of pionic deuterium. The theoretical value
fits well the experimental data. Using the cross sections for the reactions
nu_e + d -> p + p + e^- and nu_e + d -> p + n + nu_e, computed in the NNJL
model, and the experimental values of the events of these reactions, detected
by the SNO Collaboration, we compute the boron neutrino fluxes. The theoretical
values agree well with the experimental data and the theoretical predictions
within the Standard Solar Model by Bahcall. We argue the applicability of the
constraints on the astrophysical factor for the solar proton burning, imposed
by helioseismology, to the width of the energy level of the ground state of
pionic deuterium. We show that the experimental data on the width satisfy these
constraints. This testifies an indirect measurement of the recommended value of
the astrophysical factor for the solar proton burning in terrestrial
laboratories in terms of the width of the energy level of the ground state of
pionic deuterium.Comment: 10 pages, no figures, Late
Measurement of the hyperfine structure of antihydrogen in a beam
A measurement of the hyperfine structure of antihydrogen promises one of the
best tests of CPT symmetry. We describe an experiment planned at the Antiproton
Decelerator of CERN to measure this quantity in a beam of slow antihydrogen
atoms.Comment: 5th International Symposium on Symmetries in Subatomic Physics
