AB - A search is performed for the rare decay W± → π±γ in proton-proton collisions at √s = 13 TeV. Datacorresponding to an integrated luminosity of 137 fb−1 were collected during 2016 to 2018 with the CMSdetector. This analysis exploits a novel search strategy based on W boson production in top quark pairevents. An inclusive search for the W± → π±γ decay is not optimal at the LHC because of the hightrigger thresholds. Instead, a trigger selection is exploited in which the W boson originating from one ofthe top quarks is used to tag the event in a leptonic decay. The W boson emerging from the other topquark is used to search for the W± → π±γ signature. Such decays are characterized by an isolatedtrack pointing to a large energy deposit, and by an isolated photon of large transverse momentum.The presence of b quark jets reduces the background from the hadronization of light-flavor quarks andgluons. The W± → π±γ decay is not observed. An upper exclusion limit is set to this branching fraction,corresponding to 1.50 × 10−5 at 95% confidence level, whereas the expected upper exclusion limit is0.85+0.52−0.29 × 10−5.
