| Similar strategy to the one above! In principle above 10 GeV we are safe from SM low mass resonances. Below 10 GeV? Also, how low can one go in mass by playing with muon isolation. | Similar strategy to the one above! In principle above 10 GeV we are safe from SM low mass resonances. Below 10 GeV?
