Abstract: Diffractive and photon induced physics is a research area with a remarkable discovery potential at the LHC. ALICE has started a program to exploit its unique capabilities to study the subject in both proton-proton and heavy ion collisions. We discuss some aspects of a new sub-detector for the ALICE experiment at the LHC. This detector would enhance the performance of ALICE to address some relevant topics on this matter. It consists of four stations of scintillator pads that would tag the diffractive gap more efficiently. [ABSTRACT FROM AUTHOR]

Abstract: Abstract: The calorimeter system of the LHCb experiment consists of a scintillator layer (SPD), a preshower detector (PS), an electromagnetic calorimeter (ECAL) and a hadronic calorimeter (HCAL), and allows to trigger on hadron, electron and photon candidates. The time synchronization of the four sub-detectors studied with cosmic rays, LHC beam injection tests and LHC proton proton collisions is presented. Energy calibration methods for each subsystem are discussed as well. [ABSTRACT FROM AUTHOR]

Abstract: We discuss some aspects of a new sub-detector for the ALICE experiment at the LHC. This detector would enhance the capabilities of ALICE to study several topics of diffractive as well as of photon induced physics. It consists of four stations of scintillator pads that would tag the diffractive gap more efficiently. [ABSTRACT FROM AUTHOR]

Abstract: Abstract: LHCf is a high-energy physics experiment designed to study the forward production of neutral particles in proton–proton collisions at the LHC. The set-up consists of two small calorimetric systems symmetrically placed 140m away on both the sides of the ATLAS interaction point. Results from the experiment will provide valuable information to the calibration of the nuclear interaction models used in the Monte Carlo codes for air-shower simulations, which are of great importance for present and future ground-based cosmic-ray experiments. In particular, since LHCf will start taking data in the first phase of operation of the LHC (during the beam commissioning phase at energy) and will complete its data taking at the beginning of the runs (laboratory equivalent collision energy ), it will span an energy range up to the region between the “knee” and the GZK cut-off of the cosmic-ray spectrum.
