Search for inelastic dark matter-nucleus scattering with the PICO-60 CF$_{3}$I and C$_{3}$F$_{8}$ bubble chambers
PICO bubble chambers have exceptional sensitivity to inelastic darkmatter-nucleus interactions due to a combination of their extended nuclearrecoil energy detection window from a few keV to $O$(100 keV) or more and theuse of iodine as a heavy target. Inelastic dark matter-nucleus scattering isinteresting for studying the properties of dark matter, where many theoreticalscenarios have been developed. This study reports the results of a search fordark matter inelastic scattering with the PICO-60 bubble chambers. The analysisreported here comprises physics runs from PICO-60 bubble chambers usingCF$_{3}$I and C$_{3}$F$_{8}$. The CF$_{3}$I run consisted of 36.8 kg ofCF$_{3}$I reaching an exposure of 3415 kg-day operating at thermodynamicthresholds between 7 and 20 keV. The C$_{3}$F$_{8}$ runs consisted of 52 kg ofC$_{3}$F$_{8}$ reaching exposures of 1404 kg-day and 1167 kg-day running atthermodynamic thresholds of 2.45 keV and 3.29 keV, respectively. The analysisdisfavors various scenarios, in a wide region of parameter space, that providea feasible explanation of the signal observed by DAMA, assuming an inelasticinteraction, considering that the PICO CF$_{3}$I bubble chamber used iodine asthe target material.
