The integrated luminosity of this GlueX experiment was about $320~\\mathrm{pb^{-1}}$. The fits show that destructive interference involving an $S$-wave resonance and associated non-resonance background produces a sharp dip structure about $75~\\mathrm{MeV}$ below the LHCb mass, in the same location as a similar structure is seen in the data.
