Abstract

A search for the exclusive hadronic decays Formula Presented, Formula Presented, and Formula Presented is performed using up to Formula Presented of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of Formula Presented. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the Formula Presented boson mass through fully reconstructed decay products. The search results in the most stringent upper limits to date on the branching fractions Formula Presented, Formula Presented, Formula Presented at 95% confidence level.
