The LHC-forward (LHCf) experiment, situated at the LHC accelerator, has measured neutral particles production in a very forward region (pseudo-rapidity > 8.4) in proton-proton and proton-lead collisions. The main purpose of the LHCf experiment is to test hadronic interaction models used in cosmic rays experiments to imulate cosmic rays induced air-showers in Earth’s atmosphere.
The experiment is composed of two independent detectors located at 140m from the ATLAS interaction point (IP1) on opposite sides ; each detector is composed of two sampling calorimeters.
Latest physics results from p-p and p-Pb collisions (at √s = 7 TeV and 5.02 TeV respectively) will be discussed in this paper ; in particular, the inclusive energy spectra of neutrons in p-p collisions and the transverse momentum spectra of neutral pions for different pseudo-rapidity ranges in p-Pb collisions will be shown.
