The FPD can identify neutral pions produced at large pseudorapidity (3 < eta < 4). In general, forward jets arise from asymmetric partonic collisions, typically involving a quark from one beam and a gluon from the other. For d+Au interactions, particle detection with the FPD can test models of gluon saturation.
The FPD can identify neutral pions produced at large Feynman x (xF > 0.2) and moderate transverse momentum (pT < 4 GeV/c). For collisions of transversely polarized protons, this kinematic range may have large analyzing powers. There are many references to this.
