Semihard scattering unraveled from collective flow at the SPS

A study of elliptic flow and two-particle azimuthal correlations of charged particles (0.5 <p/sub T/< 2.5 GeV/c) and high-pcollisions at 158A GeV/c. close to midrapidity, is presented. Elliptic flow (nu/sub 2/) rises linearly with p/sub T/ to a value of about 10% at 2 GeV/c. Beyond p/sub T/app...

description A study of elliptic flow and two-particle azimuthal correlations of charged particles (0.5 <p/sub T/< 2.5 GeV/c) and high-pcollisions at 158A GeV/c. close to midrapidity, is presented. Elliptic flow (nu/sub 2/) rises linearly with p/sub T/ to a value of about 10% at 2 GeV/c. Beyond p/sub T/approx.1.5 GeV/c, the slope decreases and possibly indicates a nu/sub 2/ saturation at high pGeV/c exceed the nu/sub 2/ values by about 60% in semicentral collisions. This non-flow component is attributed to near-side and away-side jetlike correlations. While the near-side peak remains constant with centrality 0.230.03 rad, as expected for fragmentation, the away- side peak experiences broadening and disappears in central collisions.
