The data correspond to an integrated luminosity of 29.4 fb−1. The tt¯ decay products are reconstructed using the central CMS detector, while forward protons are measured in the CMS-TOTEM precision proton spectrometer. An observed (expected) upper bound on the production cross section of 0.59 (1.14) pb is set at 95% confidence level, for collisions of protons with fractional momentum losses between 2 and 20%. © 2025 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/openAccessHadron-Hadron ScatteringTop PhysicsArticle10.1007/JHEP06(2024)1872-s2.0-105012442181
