J/ψ production in a quark-gluon plasma
Vanyashin A. V. , Emel'yanov V. M.
The suppression of the production of J/ψ particles in a quark-gluon plasma is shown to depend on their transverse momentum qL: The fraction oiJ/φ particles with qL < 1 GeV/c in the dN /dq[ spectrum decreases by a factor ~ 5. The spectrum thus acquires a shape distinct from those corresponding to other J /ф production mechanisms.
