Abstract
A spate of remarkable new hadrons reported in 2003 may lead to unequivocal proof of states beyond conventional [Formula: see text] and qqq structure. Claimed baryonic states Θ+, Φ, and [Formula: see text] would consist of five quarks, and new [Formula: see text]-states and/or X(3872) might contain four quarks. I review efforts to search for and study this "new" spectroscopy in [Formula: see text]-collisions with the CDF II detector. Pentaquark searches are negative, and no evidence for exotic analogs of DsJ-states was found. CDF has confirmed the X(3872). My main focus is the production and decay properties of the X(3872), and its possible interpretations.
