<center>HAD_01 : *Measurements of Jets and Photons in Heavy Ion Collisions at the Highest Beam Energy during the LHC-Run 2 by ALICE* </center>

_Summary_ :<br>
Physics analyses using jets, photons, and hadrons measurements in the LHC Run-2 (2015-2018) for Pb-Pb, p-p, p-Pb collisions, will be carried out by the French-Japanese collaboration in the ALICE experiment. A newly installed detector from Run-2 for di-jet measurement, DCal, will be commissioned and operated by the French-Japanese team. Physics analysis will be using DCal as well as the existing calorimeters; EMCal and PHOS. It is expected to gain a deeper understanding of the fundamental properties of the Quark Gluon Plasma (QGP) through unique gamma and jet tomography measurements.

<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.
