...er (Yale University) • P. Zerwas (DESY) • C. Zhang (IHEP, Beijing) • K. Zuber (University of Dortmund) • F. Zwirner (University of Rome) 3. Naming scheme for hadrons We introduced in the 1986 edition =-=[2]-=- a new naming scheme for the hadrons. Changes from older terminology affected mainly the heavier mesons made of u, d, and s quarks. Otherwise, the only important change to known hadrons was that the F...

...ver, since 〈χ 2 r 〉 is not a fixed quantity (it is somewhere between N k and N k−1), we do not know how to evaluate this expression. Instead we define S 2 r = 1 N k N k � k=1 � �2 Rrk − Rr (δRrk) 2 , =-=(4)-=- − (δRr) 2 where δRr is the fitted error for ratio r. With this definition the expected value of S2 r is one. The fit is redone using errors for the branching ratios that are scaled by the larger of S...
