Early results of the LHCf Experiment and their contribution to Ultra-High-Energy Cosmic Ray Physics

Understand

LHCf is an experiment dedicated to the measurement of neutral particles emitted in the very forward region of LHC collisions.

• The physics goal is to provide data for calibrating hadron interaction models that are used in the study of Extremely High-Energy Cosmic-Rays.
• The LHCf experiment acquired data from April to July 2010 during commissioning time of LHC operations at low luminosity.
• Production spectra of photons and neutrons emitted in the very forward region ($\eta>$ 8.4) have been obtained.
