Title: I. Theorie/Theory Current Algebra, PCAC, Its Anomaly, and the Two-Photon Process (Soft-Pion Production by Two Photons)

Abstract

Here, various applications of the current algebra, PCAC (partially conserved axialvetor current hypothesis) and its anomaly to the hadron production by two photons γ + γ → hadrons are reviewed. They include the processes (1) γ + γ → π 0, η, η' (or X 0) and ε (2) γ + γ → 3 π 0, π + + π - + π 0, and (3) γ + γ → nπ + + nπ - (n = 1, 2, 3, ...), where all produced pions are soft. Asymptotic behavoir of the processus (4) γ* + γ* → π + + π - and (5) γ* + γ* → π 0 for highly virtual photons is also discussed.
