We report the first results of the ALICE experiment on heavy-flavour measurements at forward(1) rapidity (-4 < eta < -2.5) in the muonic decay channel. The data have been collected during the proton-proton collisions at root s = 7 TeV. In the ALICE program, the heavy-flavour detection in nucleon-nucleon interactions has a central role both as a test of perturbative QCD and as a baseline for the study of matter at high energy densities in heavy-ion collisions.
The extraction of the heavy-flavour signal in the inclusive muon spectra requires the subtraction of the contribution from the decay-in-flight of light hadrons and from particles produced in the absorption elements. The details of the analysis and the main results will be discussed in this paper.
