  ALICE is the experiment dedicated to the study of the quark gluon plasma in
heavy-ion collisions at the CERN LHC. Improvements of ALICE sub-detectors are
envisaged for the upgrade plans of year 2017. The Muon Forward Tracker (MFT) is
a proposal in view of this upgrade, motivated both by the possibility to
overcome the intrinsic limitations of the Muon Spectrometer, and by the
possibility to perform new measurements of general interest for the whole ALICE
physics. The measurement of the offset of single muons and dimuons will permit
to disentangle open charm ($c\tau \sim 150 \mu$m) and beauty ($c\tau \sim 500
\mu$m) production. The MFT, thanks to its tracking capabilities, will allow to
improve the mass resolution of the resonances for a better separation between
$\rho/\omega$ and $\phi$, $J/\psi$ and $\psi'$, and $-$ to a lesser extent $-$
$\Upsilon$ family resonances. In addition, it will help to reject a large
fraction of muons coming from pion and kaon decays, improving the signal over
background ratio. In order to evaluate the feasibility of this upgrade, a setup
composed by five silicon planes was simulated within the AliRoot framework. In
this report, we present preliminary results on the MFT performances in a
low-multiplicity environment.
