Search for central exclusive production of top quark pairs with the CMS and TOTEM experiments
A search for central exclusive production of top quark pairs $t\bar{t}$ is presented using collision data collected by CMS and CT-PPS in 2017. A data-driven method to estimate the background from coincidences of inclusive events and pileup protons, as well as the development of a BDT classifier to s...

| Sumario: | A search for central exclusive production of top quark pairs $t\bar{t}$ is presented using collision data collected by CMS and CT-PPS in 2017. A data-driven method to estimate the background from coincidences of inclusive events and pileup protons, as well as the development of a BDT classifier to separate the exclusive top signal from the inclusive $t\bar{t}$ background. The first-ever upper limits on the cross section of exclusive $t\bar{t}$ are shown. |
