%0 Journal Article %T Probing the EOS of dense neutron-rich matter with high-energy radioactive beams %A Bao-An Li %J Physics %D 2003 %I arXiv %R 10.1016/j.nuclphysa.2004.01.109 %X Nuclear reactions induced by high energy radioactive beams create a transient state of nuclear matter with high density and appreciable neutron to proton asymmetry. This will provide a unique opportunity to explore novel properties of dense neutron-rich matter and the isospin-dependence of the nuclear equation of state (EOS). Here we study the $\pi^-/\pi^+$ ratio as a probe of the EOS of dense neutron-rich matter. %U http://arxiv.org/abs/nucl-th/0312026v1
