Description
The LHCf experiment has performed dedicated measurement of neutral particles in the very forward of LHC p-p collisions. The results in inclusive single photon spectra at 7TeV and 900GeV p-p collisions, and the pi0 transverse spectra at 7TeV p-p are presented with comparison of various hadron interaction models used for UHECR shower simulations. Also prospects in the 2012 p-Pb runs at LHC and possible future A-A runs are discussed.
Summary
The single photon spectra at 7TeV and 900GeV p-p collisions are compared with various cosmic ray interaction models such as QGSJET-II, DPMJET3, SYBILL, EPOS and PYTHIA in the very forward. The results show most of models predict too hard spectra. Similarly pi0 PT spectra in the very forward region are compared and we found EPOS shows pretty good agreement. These results will be soon feedback to UHECR experiments to refine their MC.
