摘要：
The modifications of plasmonlike excitations in hot hadronic or quark-gluon matter due to the finite size of the systems that will be produced in relativistic heavy-ion collisions are investigated. It is shown that the relevant parameter is RM2/\q\ where R is the size of the system, M is the mass of the plasmon in an infinite system, and q is its three-momentum in the plasmon. If RM2/\Q\ << 1, the plasmon excitations will not be produced. This has important implications for plasmons generated in heavy-ion collisions by electromagnetic interactions which have been suggested by some authors.
