abstract
Stimulated by the recent observation of the $X(5568)$, we study the $X(5568)$ and its partners under the tetraquark scenario. In the framework of the color-magnetic interaction, we estimate the masses of the partner states of the $X(5568)$ and discuss their decay pattern, which provide valuable information on the future experimental search of these states.

A mass splitting model anchored to X(4140) interprets LHCb's T^a_c sbar0(2900) and T_cs0*(2870)^0 as particular singly-heavy tetraquarks and forecasts several narrow states.
