Description
The measurement of forward neutrons and photons is a common feature of all RHIC experiments. It was motivated by the role of forward neutrons in event characterization and in accessing diffractive phenomena in nuclear collisions.
In pp collisions at RHIC measurement of forward neutrons has been useful:
since ~40% of the time the leading baryon in a non-diffractive collision is a neutron, measurement of neutron x_F between 0.2 and 1.0 is an important complement to measurements of protons at colliders- typically in a very limited range of x_F.
I will also present results from first operation of the ATLAS zero degree calorimeter which is now extending this physics to Sqrt[s]=7 TeV.
