P. Abreu et al., A MEASUREMENT OF THE PHOTON STRUCTURE-FUNCTION F-2(GAMMA) AT AN AVERAGE Q(2) OF 12 GEV2 C(4)/, Zeitschrift fur Physik. C, Particles and fields, 69(2), 1996, pp. 223-233
The hadronic photon structure function F-2(gamma) has been measured in
the Q(2) range from 4 to 30 GeV2/c(4) and down to x values of order 0
.001, using data taken with the DELPHI detector at LEP between 1991 an
d 1993. A comparison is made with several F-2(gamma) parameterizations
with special emphasis on their low rr: behaviour. A result on the Q(2
) evolution of F-2(gamma) is presented.
