D. Deflorian et al., PHOTOPRODUCTION OF JETS AND THE VIRTUAL STRUCTURE OF THE PHOTON, Zeitschrift fur Physik. C, Particles and fields, 75(2), 1997, pp. 265-270
We compute the ratio between the direct and the resolved photon compon
ents of single jet and dijet production in ep collisions for the kinem
atical range covered by the most recent ZEUS data, We analyse the phen
omenological consequences of different models for the structure of vir
tual photons in these observables and compare them with the available
data. We also comment on the correlation between the so-called x(gamma
)(obs) and the 'true' x(gamma), that can be inferred from the data.
