Monte Carlo study of forward pi(0) production spectra to be measured by the LHCf experiment for the purpose of benchmarking hadron interaction models…
2011
Abstract The LHCf experiment aims to improve knowledge of forward neutral particle production spectra at the LHC energy which is relevant for the interpretation of air shower development of high energy cosmic rays. Two detectors, each composed of a pair of sampling and imaging calorimeters, have been installed at the forward region of IP1 to measure π0 energy spectra above 600 GeV. In this paper, we present a Monte Carlo study of the π0 measurements to be performed with one of the LHCf detectors for proton–proton collisions at s = 14 TeV. In approximately 40 min of operation at luminosity 0.8 × 10 29 cm - 2 s - 1 during the beam commissioning phase of LHC, about 1.5 × 104 π0 events are exp…
Early results of the LHCf experiment and their contribution to ultra-high-energy cosmic ray physics
2010
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 ($��>$ 8.4) have been obtained. In this paper preliminary results of the photon spectra taken at $\sqrt{s}$ = 7TeV are reported.
