  Recent results of the WA98 experiment with p and Pb induced reactions at 158
AGeV are presented. Azimuthal gamma-gamma correlations at high pT were studied
in search for a signal of jet-like structures. A clear indication for
back-to-back correlations can be seen in p+A with a strong dependence on the pT
of the photons and the size of the system. In Pb+Pb collisions in plane
elliptic flow has been observed. Results on transverse mass spectra of neutral
pions measured at central rapidity are presented for impact parameter selected
Pb+Pb collisions. In going from peripheral to medium central collisions there
is a nuclear enhancement increasing with transverse mass similar to the Cronin
effect, while for very central collisions this enhancement appears to be weaker
than expected.
