Linear scaling of lepton charge asymmetry in W± production in ultra-relativistic nuclear collisions from PACIAE model

Measurement of the Lepton Charge Asymmetry in W - boson Decays Produced in pp Collisions

Muon Pair Production in Relativistic Nuclear Collisions

The exclusive production of one μ+μ− pair in collisions of two ultra-relativistic nuclei is considered. We present the simple method for calculation of the Born cross section for this process. Then we found that the Coulomb corrections to this cross section (which correspond to multi-photon exchange of the produced μ with nuclei) are small while the unitarity corrections are large. This is in s...

Thermal hadron production in relativistic nuclear collisions

We present the status of the description of hadron production in central nucleus-nucleus collisions within the statistical model . Extending previous studies by inclusion of very high-mass resonances (m> 2 GeV), and the upto-now neglected scalar σ meson leads to an improved description of the data. In particular, the hitherto poorly reproduced energy dependence of theK/π ratio at SPS energies (...

Hadron Production in Relativistic Nuclear Collisions

Relativistic nucleus-nucleus collisions create a ”fireball” of strongly interacting matter at high energy density. At very high energy this is suggested to be partonic matter, but at lower energy it should consist of yet unknown hadronic, perhaps coherent degrees of freedom. The freeze-out of this high density state to a hadron gas can tell us about properties of fireball matter.

Production of Anticentauro Events in Ultra-relativistic Heavy Ion Collisions

We propose a novel method for studying the production of anticentauro events in high energy heavy ion collisions utilizing Chebyshev expansion coefficients. These coefficients have proved to be very efficient in investigating the pattern of fluctuations in neutral pion fraction. For the anticentauro like events, the magnitude of first few coefficients is strongly enhanced (≈3 times) as compared...
