Description

Observables sensitive to saturation in DIS will be reviewed. Particular triggers on final state particles in DIS make unitarity limits and saturation prominent. Perhaps surprisingly, it appears that one can even trigger on events where unitarity limits are visible for quark-antiquark dipoles, due to gluon saturation, but where quark occupancies are below saturation.
