Recently claimed \cite{dj1,dj2,FC} anomalous nuclear effects in di-jet production are analyzed in view of multiple interaction of projectile/ejectile partons in nuclear matter. We derive model--independent relations between A-dependence of…
We study the nuclear dependences of high-$p_T$ jet cross sections in one photon and one jet production in proton-nucleus collisions. We find that there exist asymmetries between the outgoing jets and photons. A convincing reason responsible…

We discuss leading charm production in connection with energy deposition in the central rapidity region. Special attention is given to the correlation between production in central and fragmentation regions. If the fraction of the reaction…
