N2 - A search for the exclusive hadronic decays πΒ±βπΒ±β’πΎ, πΒ±βπΎΒ±β’πΎ, and πΒ±βπΒ±β’πΎ is performed using up to 140ββfbβ1 of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of βπ =13ββTeV. 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 π boson mass through fully reconstructed decay products. The search results in the most stringent upper limits to date on the branching fractions β¬β‘(πΒ±βπΒ±β’πΎ)<1.9Γ10β6, β¬β‘(πΒ±βπΎΒ±β’πΎ)<1.7Γ10β6, β¬β‘(πΒ±βπΒ±β’πΎ)<5.2Γ10β6 at 95% confidence level.
