摘要:

AbstractThis is a review paper on the most important results obtained from the Algebra of Currents introduced by Gell‐Mann. It includes a detailed discussion on the derivation of sum rules (Adler‐Weisberger, Cabibbo‐Radicati, etc.), either with thep→ ∞ method and with the covariant method. Theorems for the emission of zero energy pions are discussed, and applied to leptonic and non leptonic decays of K mesons, and to the 3π decay of the η meson. More recent developments of current algebra like the gauge fields current algebra, the Weinberg sum rules, and the applications of the Bjorken's method to weak and e.m. interactions are als
