We perform a global Bayesian analysis of diffractive production in and collisions using a color glass condensate (CGC) based calculation framework. As past calculations have shown that CGC-based models typically overpredict the production in collisions at high center of mass energy, we address the question of whether it is possible to describe coherent and incoherent diffractive data from collisions at Hadron–Electron Ring Accelerator (HERA) and the LHC, and from collisions at the LHC simultaneously. Our results indicate that a simultaneous description of and data is challenging, with results improving when an overall -factor—scaling and cross sections to absorb model uncertainties—is introduced.
