“…Such spectra are sensitive to a different combination of T and η f [70,72]. Combining this information with that from the two-particle correlation functions thus allows a separation of the collective and thermal momentum components described by η f and T [39,63,121,122].…”

ABSTRACT:Two-particle momentum correlations between pairs of identical particles produced in relativistic heavy-ion reactions can be analyzed to extract the space-time structure of the collision fireball. We review recent progress in the application of this method, based on newly developed theoretical tools and new high-quality data from heavy-ion collision experiments. Implications for our understanding of the collision dynamics and for the search for the quark-gluon plasma are discussed.

“…The transverse momentum distribution of the gluons in a quark-gluon plasma of temperature T and chemical potential is therefore given by, using Eqs. (6), (8), and (9) (10) In contrast, if the boundary of the quark-gluon plasma extends to in nity, then the transverse momentum distribution is given by the Bose-Einstein form: Fig. 1 shows the transverse momentum distributions of the gluons in a quark-gluon plasma of di erent radii R o = 2; 3:5; and 5 fm, at temperature T = 200 MeV, = 0, and p z = 0.…”

The boundary of a boson system plays an important role in determining the momentum distribution of the bosons. For a boson system with a cylindrical boundary, the momentum distribution is enhanced at high transverse momenta but suppressed at low transverse momenta, relative to a Bose-Einstein distribution. The boundary e ects on systems of massless gluons and massive pions are studied. For gluons in a quark-gluon plasma, the presence of the boundary may modify the signals for the quark-gluon plasma. For pions in a pion system in heavy-ion collisions, Coulomb nal-state interactions with the nuclear participants in the vicinity of the central rapidity region further modify the momentum distribution at low transverse momenta. By including both the boundary e ect and the Coulomb nal-state interactions we are able to account for the behavior of the transverse momentum spectrum observed in many heavy-ion experiments, notably at low transverse momenta.

Transverse mass distributions of neutral pions from $^{208}$ Pb-induced reactions at 158 $\cdot A$ GeV

Abstract. Results on transverse mass spectra of neutral pions measured at central rapidity are presented for impact parameter selected 158·A GeV Pb + Pb, and Pb + Nb collisions. The distributions cover the range 0.5 GeV/c 2 ≤ mT − m0 ≤ 4 GeV/c 2 . The change of the spectral shape and the multiplicity with centrality is studied in detail. In going from p+p to semi-peripheral Pb+Pb collisions there is a nuclear enhancement increasing with transverse mass similar to the well known Cronin effect, while for very central collisions this enhancement appears to be weaker than expected.
