Analysis of the $B^{+}\to J/\psi \varphi K^{+}$ data at low $J/\psi \varphi$ invariant masses and the $X(4140)$ and $X(4160)$ resonances

Abstract

We have studied the $J/\psi \varphi$ mass distribution of the $B^{+}\to J/\psi \varphi K^{+}$ reaction from threshold to about 4250 MeV, and find that one needs the contribution of the $X(4140)$ with a narrow width, together with the $X(4160)$ which accounts for most of the strength of the distribution in that region. The existence of a clear cusp at the $D_s^{\ast }{\bar{D}}_s^{\ast }$ threshold indicates that the $X(4160)$ resonance is strongly tied to the $D_s^{\ast }{\bar{D}}_s^{\ast }$ channel, which finds a natural interpretation in the molecular picture of this resonance.
