Description
The goal of the LHCf experiment is to provide precise measurements of the spectra of neutral particles produced in the very forward region at LHC. These measurements are of fundamental importance since provide a calibration tool to tune the hadronic interaction models used by ground-based cosmic rays experiments up to the highest energy currently available at accelerator facilities. In order to achieve this goal, LHCf makes use of two small sampling calorimeters installed at ±140m from LHC IP1, so that it can detect neutral particles produced by p-p collisions having pseudo-rapidity η > 8.4.
LHCf has taken data in p-p collisions at different energies (√s = 0.9 TeV, 2.76 TeV, 7 TeV and 13 TeV) and in p-Pb collisions (√sNN = 5.02 TeV). In this talk, a summary of the main results achieved by the Collaboration will be given showing the comparison with Monte Carlo model predictions with particular emphasis to the π0 spectra which offer the possibility to study pT and pz spectra, to test Feynman scaling hypothesis and to estimate the nuclear modification factor.
