"Hadron production in electron-positron storage rings", a reviewV. M. BUDNEV, I. F. GINZBURG, G. V. MELEDIN and V. G. SERBO

This review is devoted to the three general problems : 1. Physics of the process γγ → h (hadrons). 2. Methods of extracting the information on the process γγ → h. 3. The other channels of the hadron production and background. In the section concerning physics of the process γγ → h, we limit ourselves to a short consideration of interesting reaction channels and domains of variables (photon "masses" and their summary energy) and review the principal theoretical ideas. The problem of extracting the information on the process γγ → h is a central one in the review. Different versions of the experimental set-ups both associated with recording the scattered electrons and without it are considered here in detail. The simple approximate expressions are obtained for corresponding contributions to the cross section. In conclusion, various sources of the background are listed and the corresponding estimates are given.
