Can the X(4350) narrow structure be a $1^{-+}$ exotic state?

Raphael M. Albuquerque, Jorgivan M. Dias, Marina Nielsen

Using the QCD sum rules we test if the new narrow structure, the X(4350) recently observed by the Belle Collaboration, can be described as a $J^{PC}=1^{-+}$ exotic $D_s^{\ast }{D}_{s0}^{\ast }$…
