Studies of High Density Fluctuations in Nuclei and their Implication
in the properties of Cold-Dense Nuclear Matter
Abstracr:
Theoretical framework for investigation of high-density fluctuations in
nuclei is discussed covering kinematics of intermediate to very high
momentum transfer electro-nuclear reactions at x >1. It will be
demonstrated that at intermediate values of Q^2 and large x the
high-density fluctuations can be identified with few-nucleon short-range
correlations. Theory predicts many regularities part of which is already
observed experimentally. I will concentrate on these and several new
signatures and will argue why they are unambiguously predicting the dominance
of NN correlations. In the second part of the talk the kinematics of very
high Q^2 (> 10 GeV^2) and large x will be discussed, in which the
electro-nuclear processes are dominated by deep-inelastic scattering.
I will discuss the model in which the quark-gluon degrees of freedom is
explicitly taken into account in calculation of the high density fluctuation
in DIS processes. In this model the high density fluctuation is described by
correlated double distribution of partonic distribution function of nucleons.
It will be demonstrated that in asymptotically high energies this model
approaches to the six-quark model prediction, thus representing a transitional
mechanism from NN to six-quark content of high density fluctuations in nuclei.
If time will allow I will shortly survey implication of these studies in
understanding the properties of Cold -Dense nuclear matter as Neutron Stars.
