### 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.
