Z boson production cross-section measurements in association with heavy flavour jets are important tests for perturbative quantum chromodynamics (pQCD) and the proton internal structure. This talk intends to show preliminary studies on a new cross-section measurement of the Z boson production using the full proton-proton collision data of Run-2 (√s=13 TeV) taken by the ATLAS detector at the Large Hadron Collider (LHC). The focus will be on events containing at least one jet originating from a c quark, which may be sensitive to test the hypothesis of the intrinsic charm component of the proton, and a first glance at data-to-Monte Carlo comparison distributions will be provided.
