The unexpected detection of the muon could be considered the first puzzle that this elementary particle posed to the physics. To this conundrum follows a series of new puzzles that are briefly analyzed. Then it is discussed the present muon puzzle related to the number of muons that are experimentally determined in cosmic rays that is much larger than the number predicted by the available hadron interaction models. Finally, a model based upon the strangeness enhancement at high energies called “piKswap” that is able to reconcile theory and experiment is presented. The model has precise predictions to be confronted with near future experiments related with the measurements of neutrino fluxes as FRASER and the projected Forward Physics Facility (FPF).
