Hydrodynamics of Hadronic Matter Produced in Ultrarelativistic Nucleus-nucleus Collisions
TL;DR: In this paper, the energy density, fluid velocity and net baryon number density of the hadronic matter were determined by numerically integrating these equations, which can be used to assess the possibility of attaining the quark-gluon plasma phase as well as to discuss its diganosis.

QCD angular correlations for muon pair production
TL;DR: In this paper, the angular distribution of muons is discussed in the framework of a QCD treatment of muon pair production in hadron-hadron collisions, and the predicted angular effects are independent of the infrared behavior of QCD.

Quark gluon plasma in ultrarelativistic nucleus-nucleus collisions
K. Kajantie,Risto Raitio +1 more
TL;DR: In this article, the space region in which quark gluon plasma is likely to appear in ultrarelativistic nucleus-nucleus collisions, is explicitly calculated by numerically integrating relativistic hydrodynamic equations appropriate for the process.

Study of the 1500 and 1700 MeV enhancements in the pπ+π− mass in the reaction pp→ppπ+π− at 19 GeV/c
H. Johnstad,R. Møllerud,L. Veje,S. Ljung,H.I. Miettinen,Risto Raitio,J.K. Tuominiemi,T. Jacobsen,S.O. Sørensen,L. Granström,S. O. Holmgren,U. Svedin,N. Yamdagni +12 more
TL;DR: In this article, the 1500 MeV and 1700 MeV enhancements observed in the pππ system were analyzed and it was found that the 1500 MEV effect is not a pure angular momentum state.

Combinatorial Preon Model for Matter and Unification
TL;DR: In this article, a preon model for quarks and leptons based on constituents defined by mass, spin and charge is considered and the color and weak interaction gauge structures can be deduced from the preon bound states.
