Probing cold dense nuclear matter.
The protons and neutrons in a nucleus can form strongly correlated nucleon pairs. Scattering experiments, in which a proton is knocked out of the nucleus with high-momentum transfer and high missing momentum, show that in carbon-12 the neutron-proton pairs are nearly 20 times as prevalent as proton-proton pairs and, by inference, neutron-neutron pairs. This difference between the types of pairs...
متن کاملProbing Dense Partonic Matter at RHIC
1. Introduction Comprehensive analysis of the experimental data collected by the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) during the first three years of operation has shown that a new state of matter is created in Au+Au collisions. This matter cannot be described in terms of ordinary color neutral hadrons [1]. Strongly interacting systems under extreme conditions of temp...
متن کاملProbing Dense Matter with Strange Hadrons
The signature of quark-gluon plasma is hard to identify, since the final state observed in the laboratory always consists of the same particles, irrespective of the transitional presence of the deconfined state. What changes is the detailed composition of the observed produced particle abundance. We consider here strangeness , and the pattern of strange hadron production at SPS and RHIC which o...
متن کاملAspects of Cold Dense Quark Matter
This thesis is devoted to properties of quark matter at high density and (comparatively) low temperature. In nature matter under these conditions can possibly be found in the interior of (some) neutron stars. Under “normal” conditions quarks are confined in the hadrons. Under the extreme conditions in the core of a neutron star, however, the strong interaction between the quarks becomes weaker ...
متن کاملMulti fluidity and Solitary wave stability in cold quark matter: core of dense astrophysical objects
Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...
