QUARKS IN NUCLEI
One of the most compelling questions in modern
Nuclear Physics is what role quark and gluon
degrees of freedom play in nuclear structure and
in the dynamic of nuclear matter !

Cumulative Nuclear Effect Quark-Parton
Structure Function of Nucleus
Properties of cumulative particles are determined
by the local properties of nuclear matter.
Nuclear physics beyond classical proton-neutron
model of nucleus.

JINR material and intellectual contributions to
the development and manufacture of STAR
detector and preparation of relativistic
nuclear program at RHIC were essential.
JINR Contribution and Results
JINR material and intellectual contributions
to the development and manufacture of STAR
detector and preparation of relativistic
nuclear program at RHIC are essential.
The JINR Scientific Council support of these
investigations allows to conserve, maintain
and develop JINR scientific traditions, and
obtain new fundamental results.
