<center>HAD_02: *ALICE forward upgrade for high precision high statistics single and Di-Muon measurements at the LHC* </center>

_Summary_:<br>
Quantum Chromo-Dynamics (QCD) of the strong interaction predicted a new state of matter of quarks and gluons at high energy density or at high baryo-chemical potential, where those elementary particles are released from usual confinement in hadrons. This state of QCD matter, called Quark Gluon Plasma (QGP), has been reproduced and discovered via high energy nucleus-nucleus collisions. Leptons and photons have been recognized as the most promising probes to investigate the QGP properties without disturbed by final state strong interaction. Forward muons at LHC are especially powerful since the physics region of interest and the technical region of covered kinematics overlap at
the highest ever collision energy. We will build, install, and commission Muon Forward Tracker (MFT) with a strong collaboration between France and Japan at the ALICE experiment. It expands the physics reach of the ALICE muon spectrometer to J/psi, psi(2S), Upsilons and open beauty hadrons down to very low transverse momenta, opening unique programs at LHC.
