Description
The first observation of the concurrent production of two $\rm{J}/\psi$ mesons in proton-nucleus collisions will be presented. The analysis is performed using a dataset recorded by the CMS experiment at the LHC with the nucleon-nucleon center-of-mass collision energy at 8.16 TeV. The integrated luminosity is 174.6 $\rm{nb}^{-1}$. The measured inclusive fiducial cross section $\sigma(\rm{pPb} \to \rm{J}/\psi \rm{J}/\psi + X)$ is compared with theoretical predictions at next-to-leading-order accuracy. The contributions from SPS and DPS are separated by a fit on the kinematic variables, and the effective DPS cross section $\sigma_{\text{eff}}$ is extracted.
