Summary

The project aims at development of modern many-body approaches and

their applications to description of fundamental processes involving

atomic nuclei. The development work of the project team concentrates on

(1) novel energy-density functionals intended for beyond-mean-field

symmetry-restored description of ground and excited states

of nuclei across the whole nuclear chart in unprecedented accuracy, and

(2) calculation-efficient microscopic iterative linear-response and

no-core-configuration-interaction schemes rooted in nuclear density

functional theory. This enables efficient calculation of detailed nuclear

properties in large configuration spaces.

The developed many-body schemes will be accompanied by assessment

of predictive power and model error estimates and they are

partly validated by the measurements done at the Jyväskylä accelerator

laboratory (JYFL-ACCLAB). The implementation is boosted by the participation

of the research team in the large-scale computationally-oriented NUCLEI

SCIDAC project in the USA. The validated theoretical schemes are, in turn,

used

(i) For opening new vistas to the quantitative interpretation of the

experimental results obtained at the JYFL-ACCLAB in nuclear spectroscopy,

nuclear Q-value measurements and nuclear decays of astrophysical relevance.

(ii) For interpreting measurements of nuclear muon-capture rates and

charge-exchange reactions at RCNP (Research Center for Nuclear Physics) in

Osaka, Japan.

(iii) For cutting-edge applications to nuclear astrophysics

(iv) For neutrino- and dark-matter-related problems of fundamental physics,

sheding light on neutrino properties, basic features of weak interactions

and sensitivities of neutrino- and dark-matter telescopes from new

perspectives, thus contributing strongly to neutrino and dark-matter physics

and to the physics beyond the Standard Model.
