If. Ginzburg et al., THE 3RD-ORDER PROCESSES WITH W-PRODUCTION AND Z-PRODUCTION IN GAMMA-EAND GAMMA-GAMMA COLLISIONS, Physics of atomic nuclei, 56(11), 1993, pp. 1481-1486
We calculate with the help of the CompHEP package, the total cross sec
tions for production of W and Z bosons in gammae and gammagamma collis
ions in the third order in the electroweak coupling constant at the tr
ee level. We compare them with estimates obtained by simple approximat
ion methods to see their accuracy for this class of processes. We give
a preliminary physical analysis of the results.
