Elliptic flow of Eta and .pi..sup.o./sup. mesons in heavy-ion collisions at 2 A GeV.

Original language description

Azimuthal distributions of both Eta and .pi..sup.o./sup. mesons emitted at midrapidity are studied in collisions of 1.9 A GeV .sup.58./sup.Ni+.sup.58./sup.Ni and 2 A GeV .sup.40./sup.Ca+.sup.nat./sup.Ca. The observed anisotropy corresponds to a negativeelliptic flow signal for Eta mesons, indicating a preferred emission perpendicular to the reaction plane. In contrast, only small azimuthal anisotropies are observed for .pi..sup.o./sup. mesons. This may indicate that Eta mesons freeze out earlier from the central interactiregion than pions.
