Results from Pion-Carbon Interactions Measured by NA61/SHINE for Improved Understanding of Extensive Air Showers

Understand

The interpretation of extensive air shower measurements, produced by ultra-high energy cosmic rays, relies on the correct modeling of the hadron-air interactions that occur during the shower development.

• The majority of hadronic particles are produced at equivalent beam energies below the TeV range.
• NA61/SHINE is a fixed target experiment using secondary beams produced at CERN at the SPS.
• Hadron-hadron interactions have been recorded at beam momenta between 13 and 350 GeV/c with a wide-acceptance spectrometer.
