“…It is reported from LHCf [61] that nuclear modification factor of forward neutral pion in proton-lead collisions at √ s N N = 5.02 TeV exhibits strong suppression, and it increases with transverse momentum. However, hadronic interaction model predictions show almost flat p T dependence.…”

We develop a Monte-Carlo event generator based on combination of a parton production formula including the effects of parton saturation (called the DHJ formula) and hadronization process due to the Lund string fragmentation model. This event generator is designed for the description of hadron productions at forward rapidities and in a wide transverse momentum range in high-energy proton-proton collisions. We analyze transverse momentum spectra of charged hadrons as well as identified particles; pion, kaon, (anti-)proton at RHIC energy, and ultra-forward neutral pion spectra from LHCf experiment. We compare our results to those obtained in other models based on parton-hadron duality and fragmentation functions.PACS numbers: 24.85.+p,12.38.Mh

“…One of the most significant results achieved from Run I data is the measurement of inclusive production cross section of forward neutral pions [6,7,8], indirectly reconstructed from the detection of the two γs originated in the decay. There are at least two reasons for this importance.…”

The main aim of the LHCf experiment is to provide precise measurements of the production spectra relative to neutral particle produced by high energy proton-ion collisions in the very forward region. This information is necessary in order to test and tune hadronic interaction models used by ground-based cosmic rays experiments. In order to reach this goal, LHCf makes use of two small sampling calorimeters installed in the LHC tunnel at ±140 m from IP1, able to detect neutral particles having pseudo-rapidity η > 8.4. In this paper we will present the current status of the LHCf experiment, regarding in particular the first analysis results from data taking relative to p-p collisions at √ s = 13 TeV.PACS number(s): 13.85.-t, 13.85.Tp

“…This is possible thanks to two imaging and sampling calorimeter detectors [2] that are installed in regions called TArget Neutral absorber (TAN), located at a distance of 141.05 m from Interaction Point 1 (IP1). In LHC Run I and II, LHCf acquired data relative to high energy p-p and p-Pb collisions, publishing several results on forward photon [3,4], π 0 [5][6][7] and neutron [8][9][10] production. Due to the following reshaping of the TAN region, the detectors cannot operate in HL-LHC, but in Run III the LHCf experiment will reach its main scientific goals.…”

The LHC Run III will be a crucial run for the two LHC forward experiments: LHCf and FASER. In particular, Run III will be the last run where the LHCf detector can operate and, at the same time, the first run of the new FASER project. The LHCf experiment is dedicated to precise measurements of forward production, necessary to tune hadronic interaction models employed in cosmic-ray physics. In Run III, the experiment will accomplish two fundamental goals: operating in p-p collisions at √ s = 14 TeV, it will acquire a ten times larger statistics respect to Run II, in order to have precise measurements of π 0 production; operating in high energy p-O and O-O collisions, it will measure forward production in a configuration that is very similar to the first interaction of an Ultra High Energy Cosmic Ray with an atmospheric nucleus. The FASER experiment is dedicated to the search of new weakly-interacting light particles, thanks to a forward detector with proper shielding from Standard Model background. In Run III, the experiment will search for new particles with a good sensitivity, which can be strongly improved by a following possible upgrade before HL-LHC. In addition, thanks to the dedicated FASERν detector, the experiment will measure neutrino production at a collider for the first time. In this contribution, we discuss the main results expected from the LHCf and FASER experiments in Run III, highlighting their fundamental contribution in research fields that are not accessible to the four large LHC experiments.
