The ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) collaboration plans to measure the ground-state hyperfine splitting of antihydrogen in a beam at the CERN Antiproton Decelerator with initial relative precision of 10-6 or better, to test the fundamental CPT (combination of charge conjugation, parity transformation and time reversal) symmetry between matter and antimatter. This challenging goal requires a polarised antihydrogen beam with a sufficient number of antihydrogen atoms in the ground state. [...]

The LHCf forward (LHCf) experiment measures the production cross sections of neutral particles emitted to the very forward region of an LHC interaction point in order to test the hadronic interaction models used in air-shower simulations. In this proceedings, we present the neutron and $\pi^0$ spectra measured in $pp$ collisions at $\sqrt{s}$ = 13 TeV. [...]

An antihydrogen detector consisting of a thin BGO disk and a surrounding plastic scintillator hodoscope has been developed. We have characterized the two-dimensional positions sensitivity of the thin BGO disk and energy deposition into the BGO was calibrated using cosmic rays by comparing experimental data with Monte-Carlo simulations.

The LHCf experiment is an LHC experiment dedicated to measure the production spectra of forward neutral particles, photons, π0’s, and neutrons. The aim of the LHCf is to provide critical data to test and tune hadronic interaction models which are used in MC simulations for cosmic-ray air shower developments. [...]

The LHC-forward (LHCf) experiment, situated at the LHC accelerator, has measured neutral particles production in a very forward region (pseudo-rapidity > 8.4) in proton-proton and proton-lead collisions. The main purpose of the LHCf experiment is to test hadronic interaction models used in cosmic rays experiments to imulate cosmic rays induced air-showers in Earth's atmosphere..
