Abstract: The seven year Telescope Array (TA) Middle Drum hybrid composition measurement shows agreement between Ultra-High Energy Cosmic Ray (UHECR) data and a light composition obtained with QGSJetII-03 or QGSJet-01c models. The data are incompatible with a pure iron composition, for all models examined, for energies log10(E/eV)>18.4. This is consistent with previous TA results. This analysis is presented using an updated version of the pattern recognition analysis (PRA) technique developed by TA.Keywords: UHECR, cosmic rays, hybrid detection, compositionPublished in RUNG: 29.04.2020; Views: 3431; Downloads: 92 Full text (150,19 KB)
