The LHCf experiment: present status and physics results
Abstract
The main aim of the LHCf experiment is to provide precise measurements of the production spectra relative to neutral particle produced by high energy proton-ion collisions in the very forward region. This information is necessary in order to test and tune hadronic interaction models used by ground-based cosmic rays experiments. In order to reach this goal, LHCf makes use of two small sampling calorimeters installed in the LHC tunnel at 140 m from IP1, able to detect neutral particles having pseudo-rapidity η > 8.4. In this paper we will present the current status of the LHCf experiment, regarding in particular the first analysis results from data taking relative to p-p collisions at s = 13 TeV.
