Classical Fields and Heavy Ion Collisions
To understand what is happening in relativistic heavy ion colliders, currently RHIC in Brookhaven and in the future the LHC at CERN, one needs to understand not only hard probes, but also bulk particle production and thermalisation. It can be argued that the large phase space densities of partons in the small-x wavefunction of the nuclei generate a hard enough momentum scale to allow weak coupl...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملScreening of initial parton production in ultrarelativistic heavy-ion collisions
Screening of initial parton production due to the presence of on-shell partons in high-energy heavy-ion collisions is discussed. It is shown that the divergent cross sections in the calculation of parton production can be regulated self-consistently without an ad hoc cut-off, and that the resultant parton production and transverse energy production rate are finite. Consequences on the energy de...
متن کاملThe initial gluon multiplicity in heavy ion collisions
The initial gluon multiplicity per unit area per unit rapidity, dN/L2/dη, in high energy nuclear collisions, is equal to fN(gμL)(gμ)/g, with μ2 proportional to the gluon density per unit area of the colliding nuclei. For an SU(2) gauge theory, we compute fN (g2μL) = 0.14 ± 0.01 for a wide range in g2μL. Extrapolating to SU(3), we predict dN/L2/dη for values of g2μL in the range relevant to the ...
متن کاملMagnetic contribution to dilepton production in heavy-ion collisions
We calculate a novel "magnetic contribution" to the dilepton spectrum in heavy-ion collisions arising from interaction of relativistic quarks with intense magnetic field. Synchrotron radiation by quarks, which can be approximated by the equivalent photon flux, is followed by dilepton decay of photons in an intense magnetic field. We argue that the "magnetic contribution" dominates the dilepton ...
