  The new charmed resonance $ D_2^*(3000) $ was observed by the LHCb
Collaboration in $ B $ decays. In this paper, by assigning it as four possible
excited states of the $ 2^+ $ family, we use the instantaneous Bethe-Salpeter
method to calculate their Okubo-Zweig-Iizuka-allowed two-body strong decays.
The results of $ 1^3F_2 $ and $ 3^3P_2 $ states deviate from the present
experimental observation while $ 2^3P_2 $ and $ 2^3F_2 $ are in the error
range. Our study also reveals that the widths of these states depend strongly
on the masses. Due to the large uncertainties and different mass input,
variable models get inconsistent conclusions at the moment. The analysis in
this work can provide essential assistance for future measurements and
investigations.
