B. Kampfer et Op. Pavlenko, TRANSVERSE-MOMENTUM DEPENDENCE OF DILEPTONS FROM PARTON MATTER PRODUCED IN ULTRARELATIVISTIC HEAVY-ION COLLISIONS, Physical review. C. Nuclear physics, 49(5), 1994, pp. 2716-2721
The M perpendicular-to scaling property of the dilepton spectrum from
early parton matter in ultrarelativistic heavy collisions is analyzed
for various mechanisms of initial parton production. If there is no es
sentially additional scale in the parton distribution, we find even fo
r strong off-equilibrium parton matter approximate scaling, while such
scales as low-momentum cutoff or parton masses cause strong scaling v
iolations.
