Description

A search for central exclusive production (CEP) of top quark pairs is presented using collision data collected by CMS and CT-PPS in 2017. A data-driven method to estimate the background from pileup protons is described, as well as the development of a BDT classifier to separate the exclusive top signal from the inclusive ttbar background. The first-ever upper limits on the cross-section of this process are shown.
