Delta /sup ++/ production and elliptic emission of K/sup +/ and pi /sup +/ in 158 A GeV Pb+Pb collisions

The Delta /sup ++/-resonance production and azimuthal angular correlations for K/sup +/ and pi /sup +/ have been studied in 158 A Ge V /sup 208/Pb+/sup 208/Pb collisions at the CERN SPS. The Delta /sup ++/ production was estimated from the invariant mass spectrum of p pi /sup +/-pairs by subtracting...

description The Delta /sup ++/-resonance production and azimuthal angular correlations for K/sup +/ and pi /sup +/ have been studied in 158 A Ge V /sup 208/Pb+/sup 208/Pb collisions at the CERN SPS. The Delta /sup ++/ production was estimated from the invariant mass spectrum of p pi /sup +/-pairs by subtracting a mixed event background. An event-by- event analysis of the azimuthal angular correlation with respect to the reaction plane shows that in semi-central collisions, K/sup +/ mesons are preferentially emitted out of the reaction plane, while pi /sup +/ mesons are emitted in the reaction plane.
