The kinematically complete breakup reaction
6He + A → n1 + n2 + 4He + A’
Correlations between fragments
in different Jacobi coordinate systems
Theoretical analysis of various angular and energy correlations of the three fragments in 6He breakup on 208Pb at collision energy 240 MeV / nucleon have been performed. The analysis has been based on a microscopic four-body distorted wave approach to breakup reactions and uses the three-body model for the nuclear structure of the two-neutron Borromean halo nucleus 6He.

12. Microscopic theoretical analysis of the 6He+p elastic and 6He+28Si reaction cross sections
The microscopic optical potential was constructed and applied [1,2] to analyse the experimental data of FLNR JINR and the other centers. We tested the three current models of 6He+p: Tanihata's, COSMA (M.Zhukov et al) and LSSM (S.Karataglidis et al).

(A) LSSM is preferable between three models of 6He;
(B) Good agreement with the data is obtained at E>40 MeV/N;
(C) At lower E the collective and removal nucleon channels to be included.

15. In-medium properties of hadrons
Relativistic σ-, ω-, - mean-field model with density-scaled hadron masses and coupling constants is generalized to finite temperatures. Thermodynamic properties of hot and dense hadronic matter are studied with this EoS.

23. OUTLOOK
A high level of traditional, well-established
methods of theoretical research is needed
to support the JINR experimental programs.
The trend for the future is to study unusual phenomena in nuclei and nuclear matter and in astrophysical applications. This requires new conceptual ideas and development of new methods.
An enhancement of the nuclear theory groups by the young
scientists in order to guarantee the theory development in future.
A progress of available computational capacities to support
considerable computational power for numerical calculations.
