Jun. 25, 2015 With a quick analysis during 13TeV data taking, LHCf clearly identified pi0 and eta mesons in the photon pair data samples.
Welcome to LHCf
LHCf is an experiment currently installed at CERN at the LHC complex.
It consists of two small calorimeters each one placed 140 meters away
from the ATLAS interaction point. Their purpose is to study forward
production of neutral particles in proton-proton collisions at
extremely low angles. The results will provide invaluable inputs to the
many air-shower Monte Carlo codes currently used for modeling cosmic
rays interactions in the Earth atmosphere. Depending on machine start
up, data will be taken from 900 GeV in the centre of mass up to 14 TeV
(laboratory equivalent collision energy of 1017eV),
thus covering an energy range up to and beyond the "knee" of the cosmic
