The-BRAHMS experiment quest for early universe phases of hadronic matter

We report BRAHMS experiment study of hadronic matter phases created at RHIC. Heavy ion collisions at RHIC energies are characterized by a high degree of transparency of colliding nuclei leading to the formation of a baryon-poor central region. An initial energy density in this zone is well above the energy density considered necessary for the formation of quark-gluon plasma. Some forward rapidity results suggest the. possible color glass condensate phase in colliding nuclei.
