Findings

Gamma-p collider option offers clear advantages.

Measurement of x(g) down to 3×10^{-6} is feasible.

Extends small x(g) exploration by two orders of magnitude.

Abstract

Potential of the LHeC for probing small x(g) region via c\bar{c} and b\bar{b} production have been investigated. Obtained results clearly show the advantage of gamma-p collider option. Measurement of x(g) down to 3\times10^{-6} seems to be reachable which is two order smaller than HERA coverage.
