Description
Back-to-back jet produced by hard parton scatterings (di-jet) is an unique and
powerful probe to quantify the properties of Quark Gluon Plasma at LHC.
In the ALICE experiment, the electromagnetic calorimeter (EMCal) provides
a crucial role to reconstruct jets with a good energy resolution, together with the information by Time Projection Chamber (TPC).
In order to enhance the capability of back-to-back jet identification and yields of jets, photons, $\pi^0$ and their correlations,
we are constructing an additional electromagnetic calorimeter, called DCal (Di-jet Calorimeter) in ALICE.
DCal has the same design of EMCal, but it will be placed on the opposite side
of the EMCal in azimuth at mid-rapidity $-0.7\lt\eta\lt 0.7$, together with the Photon Spectrometer (PHOS).
In this poster, we present the physics cases of DCal by using simulation data,
especially on jets, di-jets, hadron($\pi^0$)-jets measurements.
The current status and plan of the DCal construction, and future perspectives will be shown.
