P. Jankowski et al., Charm production at a linear e(+)e(-) and photon collider and its sensitivity to the gluon content of the photon, NUCL INST A, 472(1-2), 2001, pp. 212-216
Leading order cross-sections for the production of charm quarks, e(+)e(-) -
-> e(+)e((e) over bar )X, at high transverse momenta are calculated for bot
h linear e(+)e(-) and photon colliders. The sensitivity of this process to
the parton distribution parametrizations of real photons, especially the gl
uon content, is tested for both accelerators. (C) 2001 Elsevier Science B.V
