Phys. Rev. C 79, 035211 (2009) [6 pages]Charm and longitudinal structure functions within the Kharzeev-Levin-Nardi modelReceived 5 December 2008; published 31 March 2009 We use the Kharzeev-Levin-Nardi (KLN) model of the low x gluon distributions to fit recent HERA data on FL and F2c(F2b). Having checked that this model gives a good description of the data, we use it to predict FL and F2c to be measured in a future electron-ion collider. The results are similar to those obtained with the de Florian-Sassot and Eskola-Paukkunen-Salgado nuclear gluon distributions. The conclusion of this exercise is that the KLN model, simple as it is, may still be used as an auxiliary tool to make estimates for both heavy-ion and electron-ion collisions. © 2009 The American Physical Society URL:
