Abstract

The dependence of the production of the $X(3872)$ meson on the hadron multiplicity in pp collisions has been used as evidence against X being a charm-meson molecule. A simple modification of the comover interaction model gives excellent fits to the data from the LHCb collaboration on the multiplicity dependence of the production of $X$ and $\psi(2S)$, giving a range of compatible values for reaction rate of $X$ and comovers.
