摘要：
A spate of remarkable new hadrons reported in 2003 may lead to unequivocal proof of states beyond conventional q (q) over bar and qqq structure. Claimed baryonic states circle minus(+), Phi, and circle minus(c)(0) would consist of five quarks, and new D-8J(+)-states and/or X(3872) might contain four quarks. I review efforts to search for and study this "new" spectroscopy in pp-collisions with the CDF II detector. Pentaquark searches are negative, and no evidence for exotic analogs of D-sJ-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.
